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.
Andrew
