Hi Rick,

very interesting and useful tips for outlier identification. Seems to work beautifully, but I'm not sure what the number of leverage points means. SAS help says that the point is declared as a leverage point if the robust distance exceeds what would expected if they were chi-square distributed. If you have more outliers than the cutoff-alpha would indicate, does that mean you have heavier tails than in a multivariate standard normal distribution?
