Examine descriptive statistics of the continuous variables . ... Thus, it is unlikely that we will find large standardized DfBetas or standardized residual values. Nonetheless, the standardized DfBeta values can verify this. The values of the standardized DfBetas have been added as seven additional variables in the data set (SDB0_1 – SDB6_1).
