Hi Andrew,
Does CEM work if you remove the "if" statement? If so, you can probably get
around this bug by dropping the missing treatment variables before
performing the matching.
Hope that helps!
Cheers,
Matt

Dear CEM List,
I am attempting to run *cem* in Stata MP 14:
cem months (#15) if laac_none_base50p!=., treatment(laac_none_base50p) show
I get the following error:
cemStata(): 3301 subscript invalid
<istmt>: - function returned error
r(3301);
*My data:*
479,808 observations
*months *ranges from 1-156 and is a real number
*laac_none_base50p *is either 0 (n=1,140) or 1 (n=472,312)
Please help; I can’t find any support for this error.
