Thanks for your help Nick. Yes, both are up-to-date.

Thanks. My experiments indicate that neither the
number of predictors nor the length of their names
are problematic here, at least with Stata/SE. I can't see
what the problem is. Are your Stata executable and ados both fully
up-to-date?

The exact syntax I used was:

_b[p_rate_male]
_b[m_rate_male]", reps(1000) cluster(year_state)

Nick - thanks for the information. Here is the syntax I used.
(1) bootstrap "dprobit y x1 x2 x3 x4 x5" "_b[x1] _b[x2]",
reps(1000)
cluster(x6) -- this worked.
(2) bootstrap "dprobit y x1 x2 x3 x4 x5 x7 x8 x9 x10 ...
x50" "_b[x1]
_b[x2]", reps(1000) cluster(x6) -- this returned "invalid syntax".
The variables in (2) above include dummies and interctions
with dummies.

-whelp limits- indicates various limits.
It is always worth including examples of the
invalid syntax you used.
I doubt that the explanation of your problem lies
in the direction you are looking. The error message
you got would be normally be
produced well before trying to apply the -regress-
command. However, without indications of
what you actually typed it is difficult to help further.

Hi - I am trying to estimate a probit model with lots of
independent
variables and estimate bootstrapped standard errors for 4
variables.
Stata keeps returning "invalid syntax" when I include all the
independent variables. However, when I include only a few
variables, it
works. Does anyone know whether or not there is a limit to
the number
of variables one can include in a regression when one uses
the bootstrap command?
