Hi all,

I learnt that the Cook’sD and Studentized Residuals are used to detect influential observations and outliers in the data. Can someone please illustrate this with an example (the mathematical way to calculate it)

Hi,

If you know SAS then it would be easy to follow this link-

Other wise also , you can leave the code and look into the results and theory given.

Hope this helps.

Hi @aayushmnit

Thanks for the link. I was actually looking for something that explains these statistics with the mathematical formulae.
