Eicker-white consistent standard error
WebApr 28, 2024 · We tested and corrected the model for heteroscedasticity using heteroscedasticity-consistent standard errors (Eicker–Huber–White standard errors). This implies weighting the variances–co-variances matrix. This method, known as weighted least squares (WLS) makes the variance of the model robust and significantly reduces …
