Coefficient of Determination (R-squared) equal to 0 means that the dependent variable cannot be predicted using the independent variable. Conversely, if it equals 1, it means that the dependent of a variable is always predicted by the independent variable. So, with the addition of independent variable R2 become larger to cause smaller prediction error.
