RESEARCH QUESTIONS THAT CAN BE ADDRESSED WITH COEFFICIENT OF DETERMINATION

by Associate Professor Togar Alam Napitupulu, Ph.D

Regression analysis also generates the so called “coefficient of determination” with common symbol R2. We know that the following formula hold for regression:

\[\sum_{i = 1}^n (Y_i – \bar Y)^2 = \sum_{i = 1}^n (Y_i – \hat Y)^2 + \sum_{i = 1}^n (\hat Y – \bar Y)^2\]
