The topic of heteroskedasticity-consistent (HC) standard errors arises in statistics and econometrics in the context of linear regression and time series analysis. These are also known as heteroskedasticity-robust standard errors (or simply robust standard errors), Eicker–Huber–White standard errors (also … Meer weergeven Heteroskedasticity-consistent standard errors are introduced by Friedhelm Eicker, and popularized in econometrics by Halbert White. Meer weergeven If the regression errors $${\displaystyle \varepsilon _{i}}$$ are independent, but have distinct variances $${\displaystyle \sigma _{i}^{2}}$$, then $${\displaystyle \mathbf {\Sigma } =\operatorname {diag} (\sigma _{1}^{2},\ldots ,\sigma _{n}^{2})}$$ which can … Meer weergeven • Freedman, David A.
