Question

Quizplus · Accepted Answer

The coefficient of determination, also known as R-squared, measures the proportion of variation in the dependent variable that is explained by the independent variable(s). It is always between 0 and 1, inclusive, with a value of 1 indicating a perfect fit of the data to the model. Therefore, it is not possible for the coefficient of determination to be larger than 1 or less than 0. However, it is possible for the coefficient of determination to be less than 1 but greater than 0, indicating that the model explains only a portion of the variation in the data.
