7 Practical Guidelines for Accurate Statistical Model Building. It’s hard to lay out the steps, because at each step, you have to evaluate the situation and make decisions on the next step. If you’re running purely predictive models, and the relationships among the variables aren’t the focus, it’s much easier. Go ahead and run a stepwise regression model. Let the data give you the best prediction.
