Identification of suitable explanatory variable in goldfeld-quandt test and robust inference under heteroscedasticity and high leverage points

In the presence of heteroscedastic errors, the ordinary least squares (OLS) estimates are unbiased and consistent, but their covariance matrix estimator is biased and no...
