[Type text] Page 1 Multiple Linear Regression h Models the relationship between many quantitative variables h If we can model the relationship between two quantitative variables, we can use a set of variables, Xs, to predict another variable, Y. h h Example. Reaction time of braking can be a result of o Age of driver o Time of day o Weather conditions h Probabilistic model that includes more than one independent variable Regression Equation y = deterministic model + random error g G ± ² ³ ± ´ µ ´ ³ ± µ ³ ·³ ± ¸ µ ¸ ³ ¹ y is the dependent variable x 1 , x 2 ,…, x k , are independent variables β i is the contribution of the independent variable x i º»g¼ G ± ² ³ ± ´ µ ´ ³ ± µ ³ ·³ ± ¸ µ ¸ is the deterministic portion of the model. Analyzing a Multiple Regression Model h Hypothesize the determinist component of the model. What variables should go into the model? o
