Hi all
I have 7 responses that I want to fit with MANOVA. I have accumulated the
responses into a matrix Y and each response has a weight vector associated with
it, so I have accumulated the weights into a matrix WT of the same dimensions
as Y. When I try
fit <- manova( Y ~ X1 + X2 + X3, weights = WT )
I get the following message:
Error in lm.wfit(x, y, w, offset = offset, singular.ok = singular.ok, :
incompatible dimensions
Does this mean I have used manova() wrongly or does it not handle a matrix of
weights as required here?
Thanks in advance and please CC replies to me
