reset: REgression Specification Error Tests

+--------+ ----+ Syntax +-----------------------------------------------------------

reset depvar indepvars [if] [in] [weight] , noconstant vce(vcetype)

+---------+ ----+ Options +----------------------------------------------------------

noconstant suppress constant term

vce(vcetype) vcetype may be ols, robust, cluster clustvar, bootstrap, jackknife, hc2, or hc3

+-------------+ ----+ Description +------------------------------------------------------

reset calculates specification tests in regression analysis.

reset can calculate 3 Specification Tests.

1- Ramsey Specification ResetF Test

2- DeBenedictis-Giles Specification ResetL Test

3- DeBenedictis-Giles Specification ResetS Test

reset can calculate Functional Form White LM Test.
