Yes, I refer to the Stata version. I think the documentation is
confusing in this point. I would write ... if you want to create a
certain number of equally space bins, say 10, place #11 in
parentheses
after the variable.
Best regards,

I guess you refer to the
Stata version of cem.
You are right, that is the number of cutpoints including the extremes,
so 11 cutpoints means 10 intervals.
Thanks for raising this

However if you have a variable with 10 values (e.g. running from 1
to
10) and you want to match on each value, the
argument `variable'
(#10)
gives you only 9 strata, whereas `variable'
(#11) gives you 10
strata.
