Refer to the REG procedure output:An analyst has selected this model as a champion because it shows better model fit than a competing model with more predictors.Which statistic justifies this rationale?
The selection criterion used in the forward selection method in the REG procedure is:
SIMULATION -A linear model has the following characteristics:*A dependent variable (y)*One continuous variable (xl), including a quadratic term (x12)*One categorical (d with 3 levels) predictor variable and an interaction term (d by x1)How many parameters, including the intercept, are associated with this model?Enter your numeric answer in the space below. Do not add leading or trailing spaces to your answer.
