A colleague of mine asked what -predict- can do after executing
-ml-. There does not seem to be any help file describing that, nor
anything in the manual that explains exactly what -predict- can do.
I have experimented, and if you estimate a linear regression with
ml, -predict foo- gives you 'linear predictions', or what is usually
called xb. It can also predict using the score option. But where is
this documented?
There doesn't seem to be a ml postestimation commands section. But,
the default predict command is ml_p.ado. It lets you use the score
option; after that, anything else gets passed to _predict. So, I
think -help predict- will tell you what the limited range of options is.
Many users are going to write their own predict command with whatever
options are appropriate for their estimation command. Other than -xb-
and a few other basics, Stata probably has no way of knowing what
other predict options would be appropriate, e.g. if you wrote a
probit command Stata wouldn't automatically know the formula for
computing predicted probababilities.
The manual does have a postestimation section for mlexp. I don't know
if any of it would apply to ml.
