  • *

    * Pseudo R2 values are the explained (i.e., reduced) variance in state rates due to the adjustment variables shown. The greater the pseudo R2, the more the model accounts for the variability among state rates due to the impact of and the control for differential distributions of the adjustment variables across states.
