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 skewness for each column.
Important! The result is given as a vector, where the k'th element denotes the skewness for the k'th column.
The skewness of any matrix can be expressed in the following way:
where n is the total number of elements on a column of that matrix, xi are the matrix's elements on that column, mean(x) is the column's mean, and s is the standard deviation of the column.
