Stepwise Regression

Every relationship you've ever had has ended badly. Fights. Ugly breakups. Snarky fights over Twitter. You've decided to make a scientific study of...why.

As part of this project, you figure out some quantitative measures to track various potential variables that could explain why everyone you've dated has eventually broken up with you. You are going to track your Personality Quotient, your Hygiene Variable, your Attractiveness Factor, and a few other more minor factors.

To discover the main cause of your love troubles, you're going to use stepwise regression. It's a statistical technique that uses regression models to test each variable in turn.

First, you run the numbers on the Personality Quotient. Then you go through the process looking at the Hygiene Variable...and so on through the list. The name "stepwise regression" comes from the fact that you run the possibilities in a step-by-step manner, taking it one variable at a time.
