I have a matrix that is 12 rows by 500 columns. I would like to take the average and standard deviation of the rows. I have devised a method to take the mean but I have limited understanding of how to take the sd. For example,
How can I add the standard deviation of each row?
Thank you very much for your help.
Code:
clear all clear mata global num_rows = 3 matrix A = (1,2,9\2,7,5\2,4,18) matrix B = J($num_rows, 1, 1) matrix sum = A*B matrix M = sum/$num_rows mat all = A,M
Thank you very much for your help.
