Can anyone please share SAS codes that will allow me to do non parametric multiple linear regression ? I have done the non parametric regression analysis (but only with 1 variable) and now I want to add few variables to it in order to do non para multiple linear regression.

Why would you do that ? that would break the rule of residual ~ N(0,1) for multiple linear regression . Maybe you should check proc glm .and Link Function should be LOG( ) .

What sort of nonparametric regression did you use for the univariate method? Are you doing this because of distributional assumptions or because of outlier and leverage point problems? Is a semiparametric method (LOESS) reasonable? The answers to these questions will help in determining a valid approach to your problem.
