WebHello Srikanth, when non-orthogonality between regressors and errors is suspected in an analysis, the endogeneity test is conducted. You don't have to use the J-statistic for endogeneity test ... One computational method which can be used to calculate IV estimates is two-stage least squares (2SLS or TSLS). In the first stage, each explanatory variable that is an endogenous covariate in the equation of interest is regressed on all of the exogenous variables in the model, including both exogenous covariates in the equation of interest and the excluded instruments. The predicted values from these regressions are obtained:
