1 Multivariable Linear Regression Application Scenario So far, we have discussed the single variable/feature regression model. Now we add more features to the housing price model, such as the number of rooms and floors, to form a multi-variable model. 1.1 Univariate Linear Regression Case Model: h theta(x) = theta 0+theta 1x 1.2 Multivariate L ...
