-mifit: svylogit ... - is the correct syntax after -miset-. The warning
message suggests to me that you have either added one dataset in
-miset- or 5 datasets that are exactly the same.
How where the datasets created, are they stored as different datasets
or stacked on top of one another in a single dataset (the latter format
seems to have become more popular, but not suitable for -miset-)?
Hope this helps,
