Efficient Estimation of Two Seemingly Unrelated Regression Equations

Author

Listed:
  • Liu, Aiyi

Abstract

We derive simpler expressions under a certain structure of design matrices for the two-stage Aitken estimates of the regression coefficients of two seemingly unrelated regression equations. The estimates are shown to have smaller variance than the ordinary least squares estimates for sufficiently large samples.
