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 statement is true. The formula for calculating the standard error of the estimate involves dividing the sum of squared residuals by the degrees of freedom, which is equal to (n-k-1) in a model with n observations and k independent variables.
