(Line three) ods select ANOVA ParameterEstimates SplineKnots; proc glmselect data=sashelp.cars; effect spl = spline(weight / details naturalcubic basis=tpf(noint) knotmethod=percentiles(5) ); model mpg_city = spl / selection=none; /* fit model by using spline effects */ output out=SplineOut predicted=Fit; /* output predicted values for graphing */ quit; Thanks, Fatemeh
