Beta is the regression coefficient which expresses the change in the dependent variable that would be produced by a positive increment of one standard deviation in the independent variable concerned. Multiple r is the relationship between the dependent and all independent variables. Adjustedr ^{2} is a modified measure of the coefficient of determination taking into account the number of predictor variables included in the regression equation.
