st: another aflogit issue
I keep running LR and then typing in aflogit for
particular variables specifying a reference level.
For some variables, no problem. For others, it says
variable not found or abbreviation is incorrect. I am
typing in the right names.
the variable xfer runs. the variables job_strain and
manual_total do not. Anyone know why?
