Create the output objects. PROC REG and PROC GLM each produce an output object named ParameterEstimates. Because the data set definition persists when the procedure ends, ODS creates a output object from each one.
proc reg data=iron; model loss=fe; title 'Parameter Estimate from PROC REG'; run; quit; proc glm data=iron; model loss=fe; title 'Parameter Estimate from PROC GLM'; run; quit;
