Hi there,

I have performed a multiple regression analysis and I am checking the assumptions. The normal probability plot is not exactly a straight line, but is it okay? If you were looking at the plot would you be satisfied hat the normality assumption is valid?

I performed an Anderson Darling test on the residuals and the residuals were found not to be normal. What would you do in this case? Would you transform some of the predictors? Would you transform them all or just some?

I'd appreciate any comments.

Thanks

John
