fode- viation is not allowed when there are gaps in the data or when lgmmiv() is specified. SE/Robust vce(vcetype) specifies the type of standard error reported, which ludes types that are derived from asymptotic theory and that are robust to some kinds of misspecification; see Methods...

We tested the hypothesis that the coefficient on2 zero by typingtest 2=0. We then tested whether the coefficient on3 also zero by typingtest 3=0, accumulate. Theaccumulateoption told Stata that this was not the start of a new test but a continuation of a previous one...
In point of fact, you do not need these macros because of other cw utilities. While you can load data sets with use, cw use provides a better alternative. The syntax is cw use filename Note the absence of a clear option—it is assumed. cw use looks in the following places for file...
