There are also methods for linear regression which are resistant to the presence of outliers, which fall into the category of robust regression. Alas, standard inequality indices are not Other work presented in the ISI session used an “epidemic algorithm” to detect outliers and impute seemingly better values. The least squared regression with the lowest meadian squared error is chosen as the final model. Nassim Nicholas Taleb, among other people, has some considered criticisms of the least square linear regression, because of the un-stability (lack of robustness) of such from the action of the outliers. Robust Regression and Outlier Detection. I had a discussion the other day about using the weights returned by boosting to do outlier detection. The next time I perform My (uninformed) hunch is that robustness of the least squares linear regression is an underdeveloped topic in the literature - so picking a method to detect lack of robustness on cost/benefit is not informed by the literature. Robust Nonlinear Optimization MATLAB Code Download Please have a look in RANSAC_4_Nonlinear.m This code is not heavily tested. Robust regression and outlier detection. Robust Nonlinear Fitting by RANSAC (Outlier Tolerent Nonlinear Regression). The basis of the algorithm is Peter J. This method simulates an epidemic in If reliable data are available on covariates of incomes from the same survey then one could use a regression-adjustment, focusing instead on the residuals. Often, however, a transformation will not eliminate or attenuate the leverage of influential outliers that bias the prediction and distort the significance of parameter estimates. I encountered a wonderful survey article, "Robust statistics for outlier detection," by Peter Rousseeuw and Mia Hubert. Motion correction algorithms may create spurious brain activations in the absence of subject motion. I am have been working on a more robust regression boosting algorithm for my undergraduate thesis. Some statistics are more robust than others to data contamination.
