I have an urgent need for a easy to use, free software to calculate the Kaiser-Meyer-Olkin (KMO) measure of matrices with ~1700 observations. I have tried to use Trujillo's m-file (http://www.mathworks.com/matlabcentral/fileexchange/loadFile.do?objectId=12736), but its not working.

Also, in case someone mentions Bartlett's Sphericity Test, the data i work on cannot be normalized, and as far as i know, Bartlett can only be applied to normalized data.

Thanks in advance
