Hi all
I am trying to run
. mfp: logit comp i.bmicat age apacheii sex dm admityear
and I got the following message
factor variables and time-series operators not allowed
if I include my categorical variable without i before the variable,
it would be
considered as continuous. Any idea how to overcome this problem.
Can you create the dummy variables yourself? Or maybe use xi, e.g.
sysuse auto
xi: mfp: regress mpg weight displacement i.foreign
Having said that, whenever Stata won't do something that I would
expect it to allow, I wonder (1) is there a good statistical reason
for not allowing me to do it, or (2) have they just not gotten around
to programming it yet?
