  • 소지역 모형들은 고정된(fixed)효과와 랜덤 효과를 포함하는 일반적 선형 혼한 모형의 특별한 경우로 간주될 수 있다. 소지역 평균이나 종계는 고정된 효과와 랜덤 효과의 일치 결합으로 표현될 수 있다. 블록 대각 공분산 구조를 갖는 선형 혼합모형(mixed model) 아래서 EBLUP은 실재문제에 있어서 많이 소지역 모형에 응용된다. 설계 가중값(design weight) 들에 의존하고 설계-일치(design consistency) 성질을 만족하는 Pseudo-EBLUP 추정량들은 소지역추정에서 합해지면 (aggregated) 사후-수정(post-adjustment)없이 벤치마킹 성질을 만족한다.

  • In Korea, the small area estimation method is currently unpopular in generating o cial statistics. Because it may be difficult to determine the reliability for small area estimation, although small area estimation ha a sufficiently good advantage to generate small area statistics for Korea. This paper inspects the method of making small area unemployment through the small area estimation method. To estimate small area unemployment we used an EBLUP-type estimator based on a logistic linear mixed model. To evaluate the EBLUP-type estimator we accomplished the real data analysis and simulation experiment from the population and housing census data. In addition, small area estimates are compared to large sample survey estimates. We found the provided method in this paper is highly recommendable to generate small area unemployment as the official statistics.

  • You 와 Rao (2002)는 소지역 추정시 유사 최량선형 비편향 예측에서 설계 가중 값을 사용하는 방법을 발전시켰다. 특히 소지역 평균들을 추정하기 위하여 유사-최량선형 비편향 예측 추정량을 제안하였다. 우리는 소지역 추정에서 실용적으로 이용되는 몇 가지 추가적인 성질을 연구하였다.

  • Small area estimation is becoming important in survey sampling due to a growing demand for reliable small area statistics. In estimating means, totals, and other parameters for small areas of a finite population, samplie sizes for small areas are typically small because the overall sample size is usually determined to provide specific accuracy at a much higher level of aggregation than that of small area. The usual direct estimators that use the only information which is gotten from the sample in a given small area provide unreliable estimates. However, indirect estimators utilize the information from the areas related with a given small area, that is, borrow strength from other related areas, and so give more accurate estimates than direct estimators. In this paper we investigate small area estimation methods such as synthetic, composite and empirical best linear unbiased prediction estimator, and apply them to real domestic data which is from the Survey of Hotels and Restaurants in In-Chon as of 1996 and then evaluate the performance of these methods by measuring average squared errors. This evaluation shows that indirect estimators, which are small area estimation methods, are more efficient than direct estimator.
