The multiple coefficient of determination R² can only be used to compare regression models that have the same set of sample observations of y_i,where i =1,2,…,n.

Question

Quizplus · Accepted Answer

The multiple coefficient of determination R² measures the proportion of variability in the dependent variable y_i that can be explained by the independent variables in a multiple regression model. It is specific to the set of sample observations used in the model and cannot be used to compare regression models that have different sets of sample observations. Therefore, the statement is true.
