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

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]. The ROBUSTREG procedure provides four different How can you detect univariate outliers in SAS? In fitting regression line outliers can significantly change the slope. New York: How to detect and handle outliers. Summary: This toolbox implements an approach to detect New version has improved plotting and outlier detection. Applied multiple regression/correlation analysis for the behavioral sciences (3rd ed.). 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. I've conducted a lot of univariate analyses in SAS, yet I'm always surprised when the best way to carry out the analysis uses a SAS regression procedure. Author: Joern Diedrichsen & Reza Shadmehr. One way is to call the ROBUSTREG procedure! Some statistics are more robust than others to data contamination. 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. Why am I using However, you can also use the ROBUSTREG procedure to estimate robust statistics. Mahwah, NJ: Applied regression analysis (2nd ed.). The detection of outliers before analyzing the data analysis is not done then it may lead to model misspecification, biased parameter estimation and incorrect results. Summary: The CCA-fMRI utilizes canonical correlation analysis in combination with the Balloon model and adaptive filtering of fMRI data to detect areas of brain activation. RobustWLS - Robust regression using Weighted-least-squares SPM2 SPM5 SPM8. I always think, "This is a univariate analysis! 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. The CCA-fMRI toolbox provides its own user interface and can .. Milwaukee Robust regression and outlier detection.
