For experiment 1, I will use all the features for the prediction

Build and train the model.
I will choose the linear regression model for the experiment 1. There are some notably reasons that made me choose linear regression model to build on this dataset. First of all, I already transform all the categorical variables in this dataset to numerical variables so linear regression model is a perfect choice for a dataset that only contains numerical variables. Moreover, the target (SalePrice) contains continuous values so linear model like linear regression is the best choice to predict this target. Furthermore, this model is simple and easy to understand and interpret.
