Good Evening All, For the past thee hours I have been working on a problem that I just can not seem to understand. With no dataset or really any information (such as X and Y values) I am at a loss. The problem: Write a macro to fit a multiple regression model where Y is identified as one macro variable, and each X is identified as another macro variable. There is more to the problem, but once I understand that I feel I can complete the rest. So far I have been thinking; % macro exercise(x, y); %let x = value 1; %let y = value 2; The second part of the problem is: Your macro should do the following: a. Fit the model. b. Plot the residuals versus each X. c. Plot the residuals versus Y. So from here I'm thinking: %let x = value 1; %let y = value 2; % macro exercise(x, y, proc sgplot data = abc, scatter x=y, y=residual_q); But I am completely off base here I feel and have no idea what to do. ...
