Robust regression and outlier detection Annick M. Leroy, Peter J. Rousseeuw
Publisher: Wiley

What is new is that MathWorks addded a wide set of support functions that simplify common analysis tasks like plotting, outlier detection, generating predictions, performing stepwise regression, applying robust regression. Outlier identification was performed with regression analysis to detect data points at or beyond 95% confidence intervals for residuals. Aggregate Industry Productivity. Regression analysis identified outliers. (2003), The Impact of Trade on Intra-Industry Reallocations and. I had a discussion the other day about using the weights returned by boosting to do outlier detection. 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. Leroy (1987), Robust Regression and Outlier. Econometrica 71 (6), 1695-1725. 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. To attest that our results were not biased due to statistical outliers, we next performed robust regression analyses using the same explanatory variables. Therefore, robust principal component analysis (ROBPCA) [23] was used to detect the outliers.

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. A different type of approach is to formulate the detection of differential splicing as an outlier detection problem, as in REAP (Regression-based Exon Array Protocol) or FIRMA (Finding Isoforms using Robust Multichip Analysis) [15,16].
