Excess kurtosis of normal distribution is zero. Generally, a distribution that has the same kurtosis as normal distribution (excess kurtosis of zero) is called mesokurtic or mesokurtotic. Negative excess kurtosis means that the distribution is less peaked and has less frequent extreme values (less ...
Kurtosis is a statistical measure that defines how heavily the tails of a distribution differ from the tails of a normal distribution. In other words, kurtosis identifies whether the tails of a given distribution contain extreme values. Along withskewness, kurtosis is an important descriptive statisti...

To capture the impact of skewness and increase kurtosis on Black's [1] European put values, we first substitute a Gram-Charlier (GC) distribution and next a Johnson distribution for Black's Gaussian one. We introduce next each distribution in the option ......
Seen from Table 1, the sample period stocks average excess return was -1.73, the market average excess return rate of -1.60. Skewness skewness of the x and y is less than zero, mild left-skewed. The peak of the two is less than 3, a low peak. Skewness and kurtosis and are not a...
Excess Kurtosis = Kurtosis – 3 Types of Kurtosis The types of kurtosis are determined by the excess kurtosis of a particular distribution. The excess kurtosis can take positive or negative values, as well as values close to zero. 1. Mesokurtic ...

The values of excess kurtosis can be either negative or positive. When the value of an excess kurtosis is negative, the distribution is calledplatykurtic. This kind of distribution has a tail that's thinner than a normal distribution. When applied to investment returns, platykurtic distributions—t...
