WebApr 24, 2009 · CMP can mimic a dozen built-in Stata commands and several user-written ones. It is also appropriate for a panoply of models previously hard to estimate. Heteroskedasticity, however, can render it inconsistent. This paper explains the theory and implementation of cmp and of a related Mata function, ghk2(), that implements the GHK … WebMost of my -cmp- command lines included either "lf" or "tech(dfp)" (the latter defaulting to d1), but not both. (For problems requiring the GHK algorithm, d1 is almost always better.) 3) Switching to use of ghk2() a new Mata implementation of the GHK algorithm for simulating higher-dimensional cumulative normal probabilities.

WebIn statistics and econometrics, the multivariate probit model is a generalization of the probit model used to estimate several correlated binary outcomes jointly. For example, if it is believed that the decisions of sending at least one child to public school and that of voting in favor of a school budget are correlated (both decisions are binary), then the multivariate … WebJun 6, 2016 · 1) If there aren't too many fixed effects, I'm optimistic it will work. However, since you're triggering use of the GHK algorithm to calculate cumulative normal densities above dimension 2, the computational burden is already pretty high. I'd build up to the full model and data set. Also, start with a modest number of GHK draws, maybe 10 or 20.
