- Abstract
- 일반화한 선형회귀모형에서 새로운 변수가 첨가되었을때 회귀계수의 일반화한 최소자승 추정치를 단계적 추정치(stepwise estimator)로 나타내었고, 첨가된 새변수에 대한 검정기준을 제시하였다.
The generalized least squares (GLS) method for estimating the parameters of a linear regression model y=Xβ+e with E[e]=0 and E[ee']=Vσ²is commonly used. When the further regressors x??s are introduced for the given GLS model y=Xβ+e, the GLS estimators for the parameters are obtained by direct calculation from the normal equation. While the GLS estimators may also be obtained by the stepwise estimation procedure.
