Question

suppose for a simple lonear regressuon mode, the coefficient of determination is .85. How should we interpret this number?

Answer 1

The coefficient of determination (denoted by R2) is a key output of regression analysis. It is interpreted as the proportion of the variance in the dependent variable that is predictable from the independent variable. An R2 between 0 and 1 indicates the extent to which the dependent variable is predictable.

Simply R2 is amount of variation in dependent variable by independent variable.
