The kurtosis value of a normal distribution is ideally 0. Negative values show that the distribution is less likely to produce extreme outliers, it is said to be playkurtic. Positive values show that the distribution is more likely to produce extreme outliers, it is said to be leptokurtic. Ca...
If you have the Statistics Toolbox, you can calculate theskewnessandkurtosisdirectly with their respective functions. If you don’t have the Toolbox, it would be relatively easy to code those functions: skewns = @(x) (sum((x-mean(x)).^3)./length(x)) ./ (var(x,1).^1.5); ...

That said, while we can use skewness to describe asymmetric distributions, there isn’t a rigorous mathematical foundation to establish what is meant by “kurtosis of an asymmetric distribution” and what is needed to measure it properly [2]. When modeling stock market volatility, Gabaix et al....
The shape of the distribution can help us identify other descriptive statistics, such as central tendency, skewness, and kurtosis. Central limit theory The central limit theorem is an often-used statistical theory stating that the distribution of averages becomes more normal, narrower, and central...
The argument can be a NumPy array, list, tuple, or similar data structure. You can omit ddof=1 since it’s the default and only matters when you’re calculating the variance. You can pass bias=False to force correcting the skewness and kurtosis for statistical bias....
The results revealed that the highest scores were attained for self-assessed and externally assessed CK. The lowest were observed in self-assessed and externally assessed TPCK. The descriptive results (mean scores, standard deviation, skewness, and kurtosis) for the four scales, CK, PCK, TK, and...

With the mean of 235.2083, median of 250, mode of 280, and standard deviation of 72.88, describe the distribution graph. With a mean of 235.2083, a median of 250, a mode of 280, and a standard deviation of 72.88, what is the skewness and kurtosis of the distribution graph?
Black-Scholes and the Volatility Skew The Black-Scholes equation assumes a lognormal distribution of price changes for the underlying asset. This distribution is also known as aGaussiandistribution. Asset prices often have significant skewness and kurtosis so high-risk downward moves happen more often...
