    On the Upper Bounds of Test Statistics for a Single Outlier Test in Linear Regression Models by Tobias Ejiofor Ugah, Emmanuel Ikechukwu Mba, Micheal Chinonso Eze, Kingsley Chinedu Arum, Ifeoma Christy Mba, Henrietta Ebele Oranye

    Published 2021-01-01
    “…A bewildering large number of test statistics have been found for testing the presence of an outlier in multiple linear regression models. Exact critical values of these test statistics are not available, and approximate ones are usually obtained by the first-order Bonferroni upper bound or large-scale simulations. …”
