Hello again, I have another question.
I am using SAS 9.4. I run a regression procedure using proc surveyreg and output residuals and predicted values which I was interested in. Now I want to obtain a predicted value of my dependent variable at a specific value of my independent variable. I thought about running regression again this time using the predicted values as my dependent valuable and use the intercept and slope from the table to manually calculate it but I am not sure this works. I used proc gplot to plot predicted values vs independent variable but could not obtain regression equation. What is the best way of doing this?
proc surveyreg data=Project1.DII_Q;
strata kstrata;
cluster psu;
weight pooled_wt;
model DII = N_EN;
output out=Project1.DII_Adj predicted=DII_pred residual = DII_resid;
run;
proc gplot data=Project1.DII_Adj ;
plot DII_pred* N_EN/regeqn;
run;
