Stata calls them that but you're repurposing a program that was
designed for other uses. I have found that the best interpretation of
those kinds of models for what I've done with them is usually to
generate predictions from the conditional distribution, which avoids
directly interpreting the coefficients. But with nonlinear models
there isn't a magic bullet for interpretation or effect size.
