    Aside from the good explanation, I appreciate the excellent sound quality. A lot of educational channels ignore that.

    Thank you for the information. How would you go about removing those studresids values that are above 3 SD from the mean from your base table? I see the observation number, but I'd like to know how I could remove those specific values from the base table.

      Why don’t you use “where *** > 3...” and create a new dataset?

    Thanks for the vid! If the default value for studentized resid to consider it as an outlier is to be greater than 3 at alpha=0.05, what can i consider if i change the alpha into 0.01 ? More power
