The formula for Adjusted R-Squared Case 1. For a multiple regression model R-squared increases or remains the same as we add new predictors to the model even if the newly added predictors are independent of the target variable and dont add any value to the predicting power of the model. The coefficient of determination or R squared method is the proportion of the variance in the dependent variable that is predicted from the independent variable.
