Also SSR (X1 ∣ X2) = 36400.6326 and SSR (X2 ∣ X1) = 3297.7917
-Referring to Table 14-4,when the builder used a simple linear regression model with house size (House) as the dependent variable and family size (Size) as the independent variable,he obtained an r2 value of 1.25%.What additional percentage of the total variation in house size has been explained by including income in the multiple regression?
