Webpoint for Cook‟s D is 4 / NObs, where NObs is the number of observations in the data set. Cook‟s D can be produced by either PROC REG or PROC GLM. The code below assumes that the NObs for observations with non-missing values for relevant variables was already calculated. R. Dennis Cook described the test known as “Cook’s Distance” in the WebCreating a SAS Unix script would be more complicated than the simplest Unix command because we need to specify: a) the SAS procedure, b) the dataset to apply the procedure to, and optionally, c) any condition and option to apply to the dataset.
