Matrix Kurtosis Calculator

   Input the matrix in the text field below in the same format as matrices given in the examples. Click the Calculate! button and find out the matrix's kurtosis for each column.

Important! The result is given as a vector, where the k'th element denotes the kurtosis for the k'th column.

The kurtosis of any matrix can be expressed in the following way:

       where n is the total number of elements on a column of that matrix, x_i are the matrix's elements on that column, mean(x) is the column's mean, and s is the standard deviation of the column.
