Hi Kevin, I need the studentized residuals. In linear models, they can be computed by using rstudent( ) function, but there seems to be no such function for nls( ) output. Alternatively, it'll be helpful if I could compute the leverage values. Best, Xingli
Need help in calculating studentized residuals/leverage values of non-linear model [nls()]

I darkly remember having read this message before. Homework still not done? http://markmail.org/message/l7ibt3b6jfu4cj2x Check Wikipedia on the definition of studentized. Dieter
