== Usage ==

The `testparm` command functionally is identical to the [[Stata/Test|test]] command. Where `test` takes ''expressions'' representing one hypothesis (or many joint hypotheses), `testparm` takes a ''variable list'' (or factor indicators) and tests the joint hypothesis that each is 0.

The following are equivalent:

{{{
testparm i(2/4).region
}}}

{{{
test (2.region=0) (3.region=0) (4.region=0)
}}}
