Stata testparm
testparm is an alternative interface to the test command.
Contents
Usage
The testparm command functionally is identical to the 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)
