I need to calculate the following quadratic form: W' *M* W where W is NxK and M is K x K However M is the result of the following quadratic form B*VARD*B' where B is N x K and VARD is a K x K. My N exceeds the 11,000 limit and so I have been trying to figure out how to use accum, glsaccum and opaccum to be able to calculate the above equations. * * For searches and help try: * http://www.stata.com/help.cgi?search * http://www.stata.com/support/statalist/faq * http://www.ats.ucla.edu/stat/stata/
