I wanted you to -tabulate- the treatment variable, so you can see whether
there are values other than 0 and 1, which would disqualify the variable for
your purposes. You could also -inspect- the var, or -assert- the values:
***
sysuse auto, clear
inspect foreign
assert inlist(foreign,0,1)
***

Dear All,
I am going to use treatment effects model to address the self-selection
problem in my models. when using "treatreg dep indep, treat (dep_t =
indep_t)", the result shows "invalid treatment values. only 0 and 1 are
allowed". in fact, my treatment indicator which is specified in () is a
dummy with 1 or 0 values only. Could you please advise me why this happens
and how i can correctly use this command?
Many thanks!
Jing
