The first step was to determine all possible combinations of predictor variables; with 11 variables, this meant a total ...
Use the RETAIN statement for two purposes: (1) to carry over values to subsequent observations, and (2) to initialize VAR to the desired value of 10 for the first observation. Then output BEFORE doubling var to carry over to the next observation: data have; do id = 1 to 10; output;...
