A BAYESIAN APPROACH IN THE DETECTION OF
OUTLIERS FOR NORMAL AND WEIBULL DISTRIBUTIONS
Jorge Alberto ACHCAR[1]
§
ABSTRACT: The problem of detection of
outliers is of great practical interest. In this paper, we present some
Bayesian methods for detection of outliers for normal and Weibull distributions
combining usual graphical procedures with posterior densities for prediction
values and predictive densities for discordant observations.
