In general,a larger R² tends to suggest that A)the estimated sample regression function explains a greater percentage of the total variation in y. B)the estimated sample regression function is more accurate. C)the estimated sample regression function explains a greater percentage of the explained variation in y. D)the estimated slope coefficient is more likely to equal the population slope coefficient.

Question

Quizplus · Accepted Answer

R² is the coefficient of determination (R-squared) which measures the proportion of the total variation in the dependent variable y that is explained by the independent variable(s). So a larger R² indicates that the estimated sample regression function explains a greater percentage of the total variation in y, which implies a better fit of the model.
