136 Houses – Criteria (list of variables) Year the house was built and age2 The number of bedrooms and Bedrooms2 The number of bathrooms and Bathrooms2 Square-footage and Square-footage2 The presence of a pool (dummy variable) Pool X Square-footage
Backward Elimination Factors with P-Values greater than .05 were eliminated Eliminated observations 104 and 132 These two observations lowered the normality P-value more than acceptable
8349 Hamilton Lane (outlier to be excluded) • $356,000.00 Zestimate • 3 years old • 4 bedrooms • 4 bathrooms • 3837 square-feet • 1 (pool)
2102 Dowelling Drive (another outlier) • $425,000.00 Zestimate • 8 years old • 5 bedrooms • 4 bathrooms • 5188 square- feet • 0 (no pool)
Regression Analysis: Price versus Age, Sq-Footage2, Pool, Age2 (Final Model) The regression equation is Price = 248306 - 19755 Age + 0.0107 Sq-Footage2 + 17513 Pool + 1310 Age2 Predictor Coef SE Coef T P VIF Constant 248306 18527 13.40 0.000 Age -19755 6043 -3.27 0.001 61.573 Sq-Footage2 0.0107076 0.0003508 30.52 0.000 1.069 Pool 17513 4119 4.25 0.000 1.088 Age2 1309.7 481.4 2.72 0.007 61.392 S = 15944.7 R-Sq = 89.2% R-Sq(adj) = 88.8%
Regression Equations Pool/No Pool The regression equation for houses with a pool: Price = 265819 - 19755 Age + 0.0107 Sq-Footage2 + 1310 Age2 The regression equation for houses without a pool: Price = 248306 - 19755 Age + 0.0107 Sq-Footage2 + 1310 Age2
Taking observation 104 and 132 allows the normality to a marginally satisfactory level of 0.024 Testing for Normality
