Example 8.14: generating standardized regression coefficients. Standardized (or beta) coefficients from a linear regression model are the parameter estimates obtained when the predictors and outcomes have been standardized to have variance = 1. Alternatively, the regression model can be fit and then standardized post-hoc based on the appropriate standard deviations.
Similarly, we obtain the regression mean square (MSR) by dividing the regression sum of squares by its degrees of freedom 1: Of course, that means the regression sum of squares (SSR) and the regression mean square (MSR) are always identical for the simple linear regression model. Now, why do we care about mean squares? Because their expected values suggest how to test the null hypothesis H 0: Î² 1 = 0 against the alternative hypothesis H A: Î² 1 â  0.
