The FastLTS algorithm (Rousseeuw & Van Driessen, ... The trimming procedure of the MCD has inspired the construction of maximum trimmed likelihood estimators (Čıžek, 2008; Hadi & Luceño, ... NettetIn our paper we start from a classical (but hard to compute) approach from robust statistics: least trimmed squares [19]. This advocates fitting a model so as to minimize the loss on only a fraction ⌧ of the samples, instead of all of them – but crucially, the subset S of samples chosen and the model to fit them are to be estimated jointly. food for yoga practice
