Apparently Factor Analysis in SAS does list wise deletion. If any individual is missing on any variable they are deleted for all variables (even if they answered those variables). I don't want to delete that many people for a number of reasons, but there does not appear to be a way in SAS to change this default.
Anyone know how to do this, or what the dangers are of including people on some variables but not others? I understand the issue of MNAR (missing not at random) but I would rather have the observations even given that.
