a correlation matrix subset where the subset avg is a maximum
Hello R group, Given a correlation matrix, I would like to obtain the best subset of pairs in the matrix of some size > n such that the mean of r for that subset is a maximum compared to any other possible subset of size > n. I've been looking at the deal and subselect packages but they don't seem to do what I need. Does anyone have any suggestions? Thanks in advance, Ryan
