Question
The number of degrees of freedom used in the divisor when computing MSE for a multiple linear regression model is equal to
a. the number of observations in the study
b. the number of independent variables in the model
c. the number of independent variables in the model
d. the number of observations, n, less one degree of freedom for the parameter appearing in the model
e. the number of observations less the number of independent variables in the model and less one for the constant term appearing in the model
Explanation / Answer
The number of degrees of freedom used in the divisor when computing MSE for a multiple linear regression model is equal to
Here the degree of freedom is the DF(error) which is equal to the number of observations less the number of independent variables in the model and less one for the constant term appearing in the model.
Option e is correct.
