% This function returns various statistics for each column vector of 
% variables in the matrix y. The list of statistics includes: the 
% number of samples; number of missing observations; minimum; 
% first quartile; median; third quartile; maximum; mean; geometric 
% mean; range; interquartile range; standard deviation; variance; 
% mean/standard deviation; skewness; kurtosis; and the Jarque-
% Bera test.
% 
% The only compulsory input to this function is y. The second 
% input arguments (out) turns the on screen display of these 
% statistics on (1 - default) or off (0).
% 
% The output argument tab is simply the table shown in the 
% command window, returned as a matrix.
