You keep talking about "dprobit" which is a little weird. I assume you mean
"dtobit" and "dtobit2"?

Subject: st: Marginal Effects in Tobit
Dear All
I'd like to compute the marg. effects and its standard errors for the
unconditional expect value in the tobit model.
(1) the standard command "tobit" in combination with "mfx" does not offer
the option to compute marginal effects for the UNCONDITIONAL expected
value (in contrast to the marg eff on the expected value conditional on
being uncensored and the marginal effect on the probability to be
uncensored).
(2) the command "dprobit" is constantly reporting me an error: "[_se] not
found"
(3) the command "dprobit2" computes the marginal effects but does not
provide the standard errors (or at least its help file does not describe
how to obtain them)
Best,
John.
