**StreetEasy**is New York City’s leading real estate marketplace — from studios to high-rises, Brooklyn Heights to Harlem. In this lesson, you will be working with a dataset that contains a … - 3
As with most machine learning algorithms, we have to split our dataset into: -

**Training set**: the data used to fit the model -**Test set**: the data partitioned away at the very start of the e… - 4
Now we have the training set and the test set, let’s use scikit-learn to build the linear regression model! The steps for multiple linear regression in scikit-learn are identical to the steps for …

When trying to evaluate the accuracy of our multiple linear regression model, one technique we can use is

**Residual Analysis**. The difference between the actual value*y*, and the predicted valu… - 9
Now let’s rebuild the model using the new features as well as evaluate the new model to see if we improved! For […] , the scores returned: […] For […] , the scores returned: […] Fo…

Great work! Let’s review the concepts before you move on: -

**Multiple Linear Regression**uses two or more variables to make predictions about another variable: […] - Multiple linear regress…
