'd' fits a linear regression with the mean function E y x p_d x d p_ d 1 x d 1 ... p_1 x p_0 So you just need to calculate.. a linear regression with the mean function E y x p_d x d p_ d 1 x d 1 ... p_1 x p_0 So you just need to calculate the R.. with the mean function E y x p_d x d p_ d 1 x d 1 ... p_1 x p_0 So you just need to calculate the R squared for that..
