Low kurtosis in a data set is an indicator that data has light tails or lack of outliers. Determining the type of Kurtosis might be tough but the solution to do the homework is easy and available with our online tutors on DO MY STATS portal. Symmetrical distribution 2. The fit of the data can be visually represented in a scatterplot. There are three types of kurtosis that can be exhibited by any distribution: Leptokurtic or heavy-tailed distribution (kurtosis more than normal distribution) Mesokurtic (kurtosis same as the normal distribution) Platykurtic or short-tailed distribution (kurtosis less than normal distribution) The distribution set follows the subtle or pale curve, and that curve indicates the small number of outliers in a distribution. Meet With Our Teacher. Kurtosis is measured by moments and is given by the following formula − Formula So, kurtosis is all about the tails of the distribution – not the peakedness or flatness. The blue line in the above picture represents a Mesokurtic distribution. Whenever the kurtosis is less than zero or negative, it refers to Platykurtic. CFI offers the Financial Modeling & Valuation Analyst (FMVA)™FMVA® CertificationJoin 350,600+ students who work for companies like Amazon, J.P. Morgan, and Ferrari certification program for those looking to take their careers to the next level. Types of Kurtosis and how to interpret. The lower the value the flatter the distribution with more spread. col = c ( 2 , 3 , 1 ) , bty = "n" ) Kurtosis can reach values from 1 to positive infinite. Data that follows a mesokurtic distribution shows an excess kurtosis of zero or close to zero. The parameters have been chosen to result in a variance equal to 1 in each case. The more the kurtosis more is the financial risk associated with the concerned data set. If the kurtosis of a distribution is greater than that of a normal distribution, then it has positive excess kurtosis and is said to be leptokurtic. Kurtosis is a measure of how differently shaped are the tails of a distribution as compared to the tails of the normal distribution. In probability theory and statistics, kurtosis (from Greek: κυρτός, kyrtos or kurtos, meaning \"curved, arching\") is a Now for kurtosis, let's take a look at three types of kurtosis. The nature of the investment to generate higher returns can also be predicted from the value of the calculated kurtosis. In the finance context, the platykurtic distribution of the investment returnsInternal Rate of Return (IRR)The Internal Rate of Return (IRR) is the discount rate that makes the net present value (NPV) of a project zero. The greater the excess for any investment data set, the greater will be its deviation from the mean. Types of Kurtosis. High excess kurtosis means that the return on the investment can swing both ways. Skewness essentially measures the symmetry of the distribution, while kurtosis determines the heaviness of the distribution tails. If there is a high kurtosis, then, we need to investigate why do we have so many outliers. The skewness measures the combined size of the two tails; the kurtosis measures the distribution among the values in these tails. In other words, it is the expected compound annual rate of return that will be earned on a project or investment. Normal distribution kurtosis = 3; A distribution that is more peaked and has fatter tails than normal distribution has kurtosis value greater than 3 (the higher kurtosis, the more peaked and fatter tails). Leptokurtic indicates a positive excess kurtosis. The Internal Rate of Return (IRR) is the discount rate that makes the net present value (NPV) of a project zero. This is calculated on the data set of the investment; the value obtained can be used to depict the nature of the investment. Kurtosis is a statistical measure that defines how heavily the tails of a distribution differ from the tails of a normal distribution. The kurtosis reveals a distribution with flat tails. Types of Kurtosis • Leptokurtic or tall distributions have usually large number of scores or values at the center of the distribution. Kurtosis is a measure of whether the data are heavy-tailed or light-tailed relative to a normal distribution. Investigate! When the excess kurtosis in flat, it means the probability of generating a high return from the investment is low and will generate high returns in only a few scenarios, regularly the return is not so high on the investment. This means that the data set follows a normal distribution. When the kurtosis distribution is calculated on any data set of a particular investment, the risk of the investment against the probability of generating returns, depending on its value and type it belongs to; the investment predictions can be made by the investment advisors. When it is negative, it indicates that the deviation of the data set from the mean is flat. The flat tails indicate the small outliers in a distribution. In terms of finance, a leptokurtic distribution shows that the return on investment may be highly volatile on a huge scale on either side. The excess kurtosis can take positive or negative values as well, as values close to zero. Therefore, an investment whose returns follow a leptokurtic distribution is considered to be risky. Kurtosis is defined as the fourth moment around the mean, or equal to: The kurtosis calculated as above for a normal distribution calculates to 3. Below is the pictorial representation of the kurtosis (all three types, each one is explained in detail in the subsequent paragraph). 1) Platykurtic - negative kurtosis value indicating a flatter distribution that normal bell curve. This can swing both the ways that are either positive returns of extreme negative returns. A normal random variable has a kurtosis of 3 irrespective of its mean or standard deviation. , then the data distribution is platykurtic. In other words, it is the expected compound annual rate of return that will be earned on a project or investment. Example: 2) Leptokurtic - positive kurtosis value indicating a peaked shaped distribution compared to normal bell curve. Kurtosis tells you the height and sharpness of the central peak, relative to that of a standard bell curve. If the curve of a distribution is more outlier prone (or heavier-tailed) than a normal or mesokurtic curve then it is referred to as a Leptokurtic curve. The concept of kurtosis is very useful in decision-making. In other words, kurtosis identifies whether the tails of a given distribution contain extreme values. A leptokurtic distribution is one that has kurtosis greater than a mesokurtic distribution. Each has a mean and skewness of zero. The spread of the frequencies is the same on both sides of the centre point of the curve. When kurtosis is positive on in other terms, more than zero, the data falls under leptokurtic. In finance, such a pattern depicts risk at a moderate level. A high kurtosis distribution has a sharper peak and longer fatter tails, while a low kurtosis distribution has a more rounded pean and shorter thinner tails. Front Slit Kurti. Join 350,600+ students who work for companies like Amazon, J.P. Morgan, and Ferrari. Positive kurtosis represents that the distribution is more peaked than the normal distribution, whereas negative kurtosis shows that the distribution is less peaked than the normal distribution. When used, these Excel functions make your financial statement analysis more dynamic. These are as follows: Platykurtic. paste ("Kurtosis = ", round (kurtosis (uni), digits = 2)), paste ( "Kurtosis = " , round ( kurtosis ( lap ) , digits = 2 ) ) ) , col = c ( 2 , 3 , 1 ) , lty = 1 , lwd = lwd1 , text . The types of kurtosis are determined by the excess kurtosis of a particular distribution. The green curve on the above picture represents the leptokurtic distribution. The leptokurtic distribution shows heavy tails on either side, indicating large outliers. From the perspective of investors, high kurtosis of the return distribution implies that an investment will yield occasional extreme returns. There are three types of distributions: In a normal bell-shaped distribution, there are tails on the left and right sides. The excess kurtosis can take positive or negative values, as well as values close to zero. Tutorials Point Let’s see the main three types of kurtosis. Mesokurtic - a normal distribution. This has been a guide to What is Kurtosis & its Definition. A large kurtosis is associated with a high level of risk for an investment because it indicates that there are high probabilities of extremely large and extremely small returns. S: hyp… There exist 3 types of Kurtosis values on the basis of which sharpness of the peak is measured. Greater the deviation from the mean means the returns are also high for that particular investment. These categories are as follows: Mesokurtic distribution. While skewness focuses on the overall shape, Kurtosis focuses on the tail shape. Such a phenomenon is known as kurtosis risk. The kurtosis coefficient is a measure of the shape of the tails. An excess kurtosis is a metric that compares the kurtosis of a distribution against the kurtosis of a normal distribution. The coefficient of kurtosis, or simply kurtosis, measures the peakedness of a distribution.High kurtosis means that values close to the mean are relatively more frequent and extreme values (very far from the mean) are also relatively more frequent. Dr. Wheeler defines kurtosis as: The kurtosis parameter is a measure of the combined weight of the tails relative to the rest of the distribution. In the area of finance, this is used to measure the volume of financial risk associated with any instrument or transaction. Here, x̄ is the sample mean. So, the further the tails are from the mean the higher the risk of getting an extremely low return and the higher the chance of getting an extremely high return. Your regular printed kurtis now come with a little twist, … Thus such an investment carried high risk. Platykurtic - a “negative” or … If a curve is less outlier prone (or lighter-tailed) than a normal curve, it is called as a platykurtic curve. If the kurtosis of data falls close to zero or equal to zero, it is referred to as Mesokurtic. The "minus 3" at the end of this formula is often explained as a correction to make the kurtosis of the normal distribution equal to zero, as the kurtosis is 3 for a normal distribution. Types of Kurtosis There are three categories of kurtosis that can be displayed by a set of data. Types of Kurtosis . The images on the right show curves for the following seven densities, on a linear scale and logarithmic scale: 1. Being platykurtic doesn’t mean that the graph is flat-topped. (C–F) The maps of the metrics obtained with a diffusion kurtosis imaging sequence at a 3-Tesla MR scanner, named fractional anisotropy (FA), mean kurtosis (MK), axial kurtosis (AK), and radial kurtosis (RK), are shown. A platykurtic distribution shows a negative excess kurtosis. CFA Institute Does Not Endorse, Promote, Or Warrant The Accuracy Or Quality Of WallStreetMojo. To calculate kurtosis in excel, there is a built-in function Kurt in excel. • It is more peaked than the normal curve since the scores are concentrated within a very narrow interval at the center. That is, data sets with high kurtosis tend to have heavy tails, or outliers. Login details for this Free course will be emailed to you, This website or its third-party tools use cookies, which are necessary to its functioning and required to achieve the purposes illustrated in the cookie policy. • "Excess coefficient", Encyclopedia of Mathematics, EMS Press, 2001 [1994] If we get low kurtosis(too good to be true), then also we need to … Kurtosis is used as a measure to define the risk an investment carries. You can easily calculate kurtosis in Excel using the Descriptive Statistics Calculator.. Coefficient of Kurtosis. D: Laplace distribution, also known as the double exponential distribution, red curve (two straight lines in the log-scale plot), excess kurtosis = 3 1. An example is the Uniform Distribution which has a kurtosis = -1.2. Platykurtosis: A statistical measure that indicates the level of peakedness of a probability distribution. The … This can be used to define the financial risk of the investment. Leptokurtic - a “positive” or tall and thin distribution (fatter tails). Also, the small outliers and flat tail indicate the less risk involved in such investments. Here you can get an Excel calculator of kurtosis, skewness, and other summary statistics.. Kurtosis Value Range. This means such an investment has the potential to generate higher returns or to deplete the investment value to a greater extent. Excess kurtosis closer to zero or a flat deviation from the mean depicts that the investment will have a lesser probability of generating high returns. Leptokurtic has heavy steep curves on both sides, indicating the heavy population of outliers in the data set. Any distribution with kurtosis ≈3 (excess ≈0) is called mesokurtic . The higher the value the sharper the peak the distribution and less spread. Several well-known, unimodal and symmetric distributions from different parametric families are compared here. To keep learning and advancing your career, the following CFI resources will be helpful: Become a certified Financial Modeling and Valuation Analyst (FMVA)®FMVA® CertificationJoin 350,600+ students who work for companies like Amazon, J.P. Morgan, and Ferrari by completing CFI’s online financial modeling classes and training program! In the era of data technology, quantitative analysis is considered the preferred approach to making informed decisions. It indicates a lot of things, maybe wrong data entry or other things. The kurtosis of a normal distribution equals 3. This means that if the data follows a normal distribution, it follows a mesokurtic distribution. • Its tails are high and long. A correlation is a statistical measure of the relationship between two variables. It is usually done with, Certified Banking & Credit Analyst (CBCA)®, Capital Markets & Securities Analyst (CMSA)®, Financial Modeling & Valuation Analyst (FMVA)™, Financial Modeling and Valuation Analyst (FMVA)®, Financial Modeling & Valuation Analyst (FMVA)®. Our tutors will easily be able to help you in determining the type of Kurtosis curve. … Before seeing how to calculate kurtosis with Excel, we will examine a few key definitions. The red line in the above graphical representation depicts a platykurtic distribution or a safe investment. Types of Skewness: Skewness may be three types 1. Buy Here – www.ajio.com. You can learn more about from the following article –, Copyright © 2021. How can I understand different types of kurtosis? A normal distribution has kurtosis exactly 3 (excess kurtosis exactly 0). A set of data can display up to three categories of kurtosis whose measures are compared against a bell curve. On the other hand, a small kurtosis signals a moderate level of risk because the probabilities of extreme returns are relatively low. Here we discuss the types of kurtosis along with its significance, advantages, and applications in Finance. In this regard, we have 3 categories of distributions: Leptokurtic. For investment advisors, kurtosis is a crucial factor in defining the investment risk associated with the portfolio of the fund. Kurtosis refers to a measure of the degree to which a given distribution is more or less ‘peaked’, relative to the normal distribution. All measures of kurtosis are compared against a standard normal distribution, or bell curve. Mesokurtic (Kurtosis = 3) — This distribution shows kurtosis of 3 near zero. is desirable for investors because there is a small probability that the investment would experience extreme returns. A distribution with kurtosis <3 (excess kurtosis <0) is called platykurtic . Kurtosis is useful in statistics for making inferences, for example, as to financial risks in an investment: The greater the kurtosis, the higher the probability of getting extreme values. – Platykurtic. The measure is best used in variables that demonstrate a linear relationship between each other. Along with skewnessPoisson DistributionThe Poisson Distribution is a tool used in probability theory statistics to predict the amount of variation from a known average rate of occurrence, within, kurtosis is an important descriptive statistic of data distribution. Positively skewed distribution 3. ... One approach is to apply some type of transformation to try to make the data normal, or more nearly normal. Kurtosis in statistics is used to describe the distribution of the data set and depicts to what extent the data set points of a particular distribution differ from the data of a normal distribution. An investment falling under platykurtic is usually demanded by investors because of a small probability of generating an extreme return. It measures the combined weight of the tails relative to the center of distribution. An investment following leptokurtic distribution is said to be a risky investment, but it can also generate hefty returns to compensate for the risk. Whenever the kurtosis is less than zero or negative, it refers to Platykurtic. However, the two concepts must not be confused with each other. In finance, kurtosis is used as a measure of financial riskFinancial Risk ModelingFinancial risk modeling is the process of determining how much risk is present in a particular business, investment, or series of cash flows. In finance, a leptokurtic distribution shows that the investment returns may be prone to extreme values on either side. Therefore, the excess kurtosis is found using the formula below: The types of kurtosis are determined by the excess kurtosis of a particular distribution. Negatively skewed distribution Symmetrical Distribution It is clear from the above diagram that in symmetrical distribution the value of mean, median and mode coincide (mean = median = mode).

It is used to determine whether a distribution contains extreme values. Quantitative analysis is the process of collecting and evaluating measurable and verifiable data such as revenues, market share, and wages in order to understand the behavior and performance of a business. It means the generated returns can either be very high or very low as per the outliers in the distribution. Learn risk analysis.
