"PCA with missing values"
Does anyone have any ideas about how to compute principal components in cases where some of the (normalized) attributes in the data have missing values, other than assuming them all to be zero? Do either of the PCA-related learners in RM have any facilities for dealing with missing values?
Thanks,
Keith
