Mastering Numerical Computing with NumPy

Using linear regression to model housing prices

In the section, we will perform multivariate linear regression for the same dataset. In contrast to the previous section, we will use the sklearn library to show you several ways of performing linear regression models. Before we start the linear regression model, we will trim the dataset proportionally from both sides by using the trimboth() method. By doing this, we will cut off the outliers:
