OVERID: Stata module to calculate tests of overidentifying restrictions after ivreg, ivreg2, ivreg29, ivprobit, ivtobit, reg3
overid computes versions of a "Sargan" or "Basmann" test of overidentifying restrictions for a number of instrumental variables estimators of an overidentified equation: a model in which the number of instruments exceeds the number of regressors. The estimators include instrumental variables regression (ivreg or ivreg2), instrumental variables probit (ivprobit, twostep), instrumental variables Tobit (ivtobit, twostep) and three-stage least squares (reg3).
