Hey guys, for educational purposes I wonder if it is possible to simulate different data sets (or specifically residuals) for a linear regression. I would like to show my students residuals with different means, variances and distributions (normal, but also not normal) in the plots created with the plot command for a lm-object. In addition it would be nice to simulate although influencal values (high cooks distance and leverage) lm.results <- lm(y~x,data) plot(lm.results) Is there an easy way to do this? Or can this be done at all (and if yes, any hints?:-) Thanks and Greetings! Friedericksen
