Hi Karthik,

see Wikipedia.
Run the analysis on the model’s residuals. I would not try to dive into critical values because many approaches have been suggested in the literature. Simply draw an xy-plot, where x is the subject’s index and y Cook’s distance. If there are “influential values” they will catch your eye. ;-)
