WebA statistic referred to as Cook’s D, or Cook’s Distance, helps us identify influential points. Cook’s D measures how much the model coefficient estimates would change if an observation were to be removed from the data set. There is one Cook’s D value for each observation used to fit the model. The higher the Cook’s D value, the ...
