Multiple Choice

Which of the following is NOT a reason nonlinear least squares is used to estimate an AR(1) model?

• A)linear least squares is not possible since the transformation that allows the new error term to be uncorrelated is no longer linear in parameters
• B)using OLS to estimate the untransformed model provides incorrect standard errors
• C)the algorithmic nonlinear optimization is less complicated to compute when error terms are correlated
• D)minimizing the sum of squares of uncorrelated error terms produces an estimator that is unbiased and consistent
