In this scenario, the real estate agent should use a simple linear regression model to analyze the relationship between these two variables because the predictor variable (square footage) is continuous. WebbIn statistics, a regression equation (or function) is linear when it is linear in the parameters. While the equation must be linear in the parameters, you can transform the predictor variables in ways that produce curvature. For instance, you can include a squared variable to produce a U-shaped curve. Y = b o + b 1 X 1 + b 2 X 12. smart health short term medical
