Subject: Need help in calculating studentized residuals/leverage values of non-linear model [nls()]
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
