Regression Analysis, R Squared, Pseudo R Squared, Adjusted R Squared, Deviance.
Linear Regression Model when it’s fitted on the (y, X) data set where y=HOUSE PRICE and X=HOUSE AGE. As you can see, the Linear Model with one variable fits a little better than the Mean Model. R² lets you quantify just how much better the Linear model fits the data as compared to the Mean Model.
