Hi everyone. Is there a way to obtain values of Cook’s distance in MLR? I am trying to identify influential observations by use of studentized residuals and Cook’s D statistics. This was kind of advised procedure for a specific problem I am currently dealing with.

Thanks in advance.

Report CancelCook’s Distance is available if you perform MLR in Design Expert, the DOE software that comes with Unscrambler.

If you build a PLS model in Unscrambler on the same data, using the full rank model (include the maximum number of components), studentized residuals are available for many Y-residual plots. For example, if you right-click on any of the PLS plots and select PLS->Residuals->General->Y-residuals vs Y-predicted. Use the toolbar button shown in the attachment to switch to studentized residuals.
