Hi! I'm running a multiple regression procedure, and we were asked to "obtain a 95% interval estimate of the mean rental rate for the following specifications of the explanatory variables: age_of_prop=5, operate_exp=8.5, vacancy_rate=0.15, total_sqft=250000. My issue is that when I create a new data set to obtain this specific information, the dataset returns 0 values, so nothing prints. Is my "AND" boolean logic correct in the IF statement, or should I be using something different to say "this and that and that"? Here I've just set up the regression procedure - it outputs to the set "results" proc reg data=cre; model rate_per_sq= age_of_prop operate_exp vacancy_rate total_sqft /stb clm cli clb alpha = .01; output out=results predicted=yhat LCLM=LCLMEAN UCLM=UCLMEAN LCL=LCLPRED UCL=UCLPRED STDP=SEmean STDI=SEi; run; Here is where I establish the new dataset. The if statement works if it states something obvious like "IF(1=1 and 2=2)," but I can't get it to return data when I want it to predict the rate_per_sq when the statement is defined as it is below. data results_1; set results; if(age_of_prop=5 AND operate_exp=8.5 AND vacancy_rate=0.15 AND total_sqft=250000); run; proc print data=results_1; run;
