The following are important steps in the stepwise method of model selection except Question 9 options: The first step is to find the variable with largest partial F statistic value (or t-statistic value) and test for H0: betak=0 If the null hypothesis is accepted, and then the variable in question is judged important and kept Next each of the remaining variables is added (separately) to the regression model that already has the rst independent variable. The variable with the highest Partial F statistic value is added. Now we have a two-variable model
