Abstract

This article aims to identify the extent to which certain factors influence housing prices. The author compares the accuracy and effectiveness of two methods Multiple Linear Regression and Random Forest in analyzing the significant factors with 1500 samples of the USA in 2014. Based on the multiple linear regression model, stepwise regression was used to remove the insignificant factor sqft-lot and analyze it to ensure the robustness of the model. Cross-validation is used to modify the random forest model’s parameters to ultimately produce the optimal model. The two models present different results. The 7 factors have different impacts on housing prices in different models. Random Forest is finally shown to be more accurate, the total impact of these seven factors on housing prices is relatively large. Bathrooms, sqft-lot and city have the biggest effects on home cost in the more precise random forest method. This study shows that in the future, more timely data can be selected and control variables can be used to further optimize. This study provides important reference and guidance for people to predict housing prices.
