\fWhich of the following describes the forward selection variable selection procedure for multiple regression? Start with no independent variables in the model. Add the independent variable with the largest F test. Then look at all models with two variables, and select the one with the largest F test. Continue this process until the model reaches the desired criterion. Start with all the independent variables in the model, then eliminate them one by one until the model reaches the desired criterion. Start with no independent variables in the model. Add the independent (9 variable with the largest F test, and keep that variable in the model. Continue adding the variables with the largest F-values until the overall model is no longer statistically significant. Which of the following criterion indicates if the model is over-specified or under- specified? A AIC B MSE C BIC D Mallow's Cp E Adjusted R2Which of the following is a good way to identify collinearity? Choose all correct answers.
