In 1964, Huber introduced M-estimation for regression. The M in M-estimation stands for "maximum likelihood type". The method is robust to outliers in the response variable, but turned out not to be resistant to outliers in the explanatory variables ( leverage points). Meer weergeven In robust statistics, robust regression seeks to overcome some limitations of traditional regression analysis. A regression analysis models the relationship between one or more independent variables and a dependent variable Meer weergeven Despite their superior performance over least squares estimation in many situations, robust methods for regression are still not … Meer weergeven The BUPA liver data have been studied by various authors, including Breiman (2001).
