Abstract

After performing callback for nonresponses in sample survey, we present an estimator of regression form using an auxiliary variable and a variance estimator using replicate method. Parametric inference method of the response probability is also presented. We research an unbiased estimator of high efficiency for the population mean and a variance estimator with consistency under callback. We also prove the validity of the theory through the simulation.

표본조사에서 무응답이 발생한 개체에 대해 재조사 실시한 후 보조변수를 사용한 회귀추정의 형태를 가지는 추정량을 제시하고 복제치 기법을 이용한 분산추정량을 연구한다. 또한 응답여부에 따른 응답확률의 모수적 추론방법도 함께 제시한다. 재조사 후 모평균에 대하여 불편성을 만족하고 효율이 좋은 추정량과 일치성을 가지는 분산추정량을 이론적으로 연구하고 모의실험을 통하여 연구의 타당성을 입증한다.
