Zero mean correlation Matrix
Hi,, I want to use the existing cor function in R but with a different way to compute the correlation method.. basically zero mean correlation. The forumula I have is 'D' <- function(c1, c2) sum(c1*c2, na.rm=T)/(sqrt(sum(c1*c1, na.rm=T))*sqrt(sum(c2*c2, na.rm=T))) I am not sure how i can modify the method cor computes its square roots and covariance matrixes? I only need to add this to get the answer -- View this message in...
