Hello- I am trying to calculate the between-group covariance matrix for a set of data for eventual Canonical Discrim Analysis. I can obtain the total covariance matrix and individual group covar matrix, but I am failing miserably at getting the between-group covar. The data set is composed of 9 variables, 3 groups and 26 observations. If anyone can provide some help, it would be extremely appreciated. I am an R newbie... please be gentle. -jh [[alternative HTML version deleted]]
