For data reconciliation, the SV regression Moreover, it is not so strict to tune the coefficients of the SV regression approach because of the robustness of the coefficients for the reconciled results. Whole host of other multivariate methods. Why am I using However, you can also use the ROBUSTREG procedure to estimate robust statistics. Therefore, robust principal component analysis (ROBPCA) [23] was used to detect the outliers. The supplementary online material for the article is being extended to contain additional information (e.g., the outlier analysis from the preceding post). 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. The ROBUSTREG procedure provides four different How can you detect univariate outliers in SAS? Furthermore, a support vector regression (SV regression) approach is proposed for simultaneous data reconciliation and gross error or outlier detection, which considers gross errors and outliers as model complexity so as to remove them. One way is to call the ROBUSTREG procedure! I think that the Lewandowsky data set may have a chance of entering the robust regression textbooks. That is the only positive aspect of the Lewandowsky research I've thus far been able to detect. I always think, "This is a univariate analysis! Robust regression is an alternative to least squares regression when data is contaminated with outliers or influential observations and it can also be used for the purpose of detecting influential observations. 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. 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.
