Computing The Kurtosis of Each Column
Syntax kurtosis(X)
See Also skewness , colrange , colmedian , colmean , sort

Description
Returns a row vector containing the kurtosis of each column of X, where X is a real, or double-precision matrix. The return value has the same type and column dimension as x.

The kurtosis of the normal distribution is 3. Distributions that are more outlier prone than the normal distribution have a kurtosis value greater than 3, distributions that are less outlier prone have a kurtosis value less than 3

Example
     X = normrnd(0., 1., 10000, 3)
     kurtosis(X)
returns
     [ 2.92882 , 3.06149 , 3.02654 ]
