Abstract [eng] |
In this paper we present estimated generalized least squares (EGLS) estimator for the coefficient vestor β in the linear regression model y=ßX+έ, where disturbance term can be heteroskedastic. For the heteroskedasticity of the changed segment type, using Monte-Carlo method, we investigate empirical properties of the proposed and ordinary least squares (OLS) estimators. The results show that the empirical covariance of the EGLS estimators is smaller than of OLS estimators. |
