As you data set is so thin, you also need to worry about the overheads
of statistical and data management procedures. If a particular -ml-
routine wants to create 10 temp variables, and you request -robust-
option that needs scores for every equation, you may see your memory
requirements double or triple. If you need to -reshape- your data set
this way or that way, it may also be problematic, although I don't
know specifically what the memory requirements are.
