search for: 44x13

...of respondents who said Yes to be mean 0 and variance 1.0, apparently doing this by brand within each attribute. He then created a matrix of 44 rows for the attributes and 13 columns for the brands. No problem with this; I can always replicate this much. But then he apparently rescaled this 44x13 matrix so that the rows all sum to zero and the columns all sum to zero. None of the row and column standard deviations are 1.0. This I can't see how to do. How can I rescale the rows and columns so that they all sum to zero? Any suggestions? Thanks, Walt ________________________ Wal...
