In recent years, researchers have proposed numerous strategies and procedures to identify the outliers. A Mathematica package PURO is introduced which implements seven methods from the latest and most respected outlier detection procedures in the statistics literature.Keywords : Regression outlier, Mathematica, Detection procedure, Masking, Swamping, Diagnostic plot.
