Question

In calculating the standard error of the estimate,  , there are (n - k - 1) degrees of freedom, where n is the sample size and k is the number of independent variables in the model.

Quizplus · Accepted Answer

This is true as the formula for calculating the standard error of the estimate includes the term (n-k-1) in the denominator to calculate degrees of freedom. Therefore, the correct formula should be (n - k - 1) degrees of freedom.
