Dear Statalisters,
in using <ivtobit> it seems that the estimated coefficients are the
marginal effects calculated at the mean values (as opposed to the
predicted values for the latent model). This is the conclusion I draw
from comparing <ivtobit> output and <mfx compute> output (when <mfx> is
obviously issued after the <ivtobit> command).
Can anyone confirm this?
I also have a question concerning the use of wildcards, such as pol*,
qual* and the like. Can wildcards be used with <ivtobit>?
Thank you very much in advance.
Giovanni
