• Consistent estimator — {T1, T2, T3, …} is a sequence of estimators for parameter θ0, the true value of which is 4. This sequence is consistent: the estimators are getting more and more concentrated near the true value θ0; at the same time, these estimators are biased.… …   Wikipedia

• Newey–West estimator — A Newey–West estimator is used in statistics and econometrics to provide an estimate of the covariance matrix of the parameters of a regression type model when this model is applied in situations where the standard assumptions of regression… …   Wikipedia

• Heteroscedasticity-consistent standard errors — In statistics, a frequent assumption in linear regression is that the disturbances u i have the same variance.
