In а multiple lineаr regressiоn, if we аdd mоre uncоrrelated independent variables, it will (1)____________ (increase or decrease) error variance. Therefore, we need to impose a penalty in the model-fit measure for adding new independent variables. As a result, we use (2)___________ (R-square or adjusted R-square) to measure goodness-of model-fit in a multiple linear regression (more than one independent variable), because it imposes a penalty for adding new independent variables.  Hint: R-squared =
