WebOn The So-Called “Huber Sandwich Estimator” and “Robust Standard Errors” by David A. Freedman Abstract The “Huber Sandwich Estimator” can be used to estimate the variance of the MLE when the underlying model is incorrect. If the model is nearly correct, so are the usual standard errors, and robustification is unlikely to help much. WebThe RA-OSELM is developed from the famous online sequential extreme learning machine algorithm, but it uses a more robust M-estimation loss function to replace the conventional least square loss function so as to suppress the incorrect online update of the learning algorithm with respect to outliers, and hence enhances its robustness in the presence of …

Its value is determined by bounding the influence of residuals in the Huber estimator, or the influence of both residuals and explanatory variables in other robust estimators, like in Hampel et al.
