Answer #1

The coefficient of partial determination measures the proportion of variation in the dependent variable that is explained by each independent variable holding all other independent (explanatory) variables constant.

The coefficient of partial determination measures the proportion of variation in the dependent variablethat is explained by each independent variable holding all other independent (explanatory) variables constant.

If we have three predictors coefficient of partial determination tells us the percent of variation not explained by one but expalined by other two.
