PCA with NA
Dear all,
(Mac OS X 10.4.11, R 2.6.0)
I have a quantitative dataset with a lot of Na?s in it. So many, that
it is not possible to delete all rows with NA?s and also not
possible, to delete all variables with NA?s.
Is there a function for a principal component analysis, that can deal
with so many NA?s.
Thanks in advance
Birgit
