抄録 Area mesh statistics is a kind of small area statistics. The area mesh data of Japan can be created in a lot of way and many of them can be downloaded, for example, from the land's value information service which is provided by Ministry of Land, Infrastructure and Transport of Japan. We developed database of these area mesh data. By using mesh navigator software (Makita Naoki, 1997), which needs to run on ProAtlas2000 and Microsoft Access2000, we displayed the mesh data on the map. What visualized on the map is very convenient. For extending the advantages of area mesh data to spatial geographical statistics, we used PostgreSQL to develop a new database of mesh data. We also develop some programs in Delphi for the analysis of area mesh data, such as Histogram, Echelon analysis, and etc.

抄録 Small Area Estimation (SAE) is the process of using statistical models to link survey outcome variables to a set of predictor variables known for small domains, in order to predict domain-level estimates. The need for detailed statistics on small area is constantly increasing. Small area estimation is becoming important in survey sampling due to a growing demand for reliable small area statistics from both public and private sectors. Bayesian hierarchical models provide a convenient framework for disease mapping and geographical correlation studies. Computation may be carried out using the freely-available WinBUGS software. Two approaches prediction to estimate total patient in small area i will be presented. For the purpose of this paper, the small area estimation in this context use data of Indnesia's population based on the 2000 census for the population of Jakarta and data of patient diarrhea from District Health Service of Jakarta. We interest to predict total patient of diarrhea as variable of interest and data population as auxiliary data from unsample for each small area.

タイトル(別表記) Variable Selection Method using Apriori Algorithm on Contingency Table
フルテキストURL 010_041_047.pdf
著者 大野 学| 垂水 共之|
抄録 We proposed a new applied method for induction of variable selection on contingency table. This method is the application of Apriori algorithm on variable selection of contigency table with iteraction. We assume that variables are dichotomous variable. We confirm that can be select variable, when minimun support is low level by using AIC on variable selection criterion.

抄録 We constructed the online analysis system of the Okayama Activity Area Survey in place since 1979. This is one way to solve the problem in case of releasing the result of a statistical survey. In this paper, we treat the detail of the structure of the system.

抄録 The present paper deals with multivariate analyses applied to the maximum likelihood estimate(s) for (the mean vector and) the covariance matrix based on incomplete data, and derives influence functions for the mean vector, the covariance matrix and some statistics in multivariate analyses. Influential directions in the sense of Cook's local influence are also derived. A numerical example is given to show the usefulness of the proposed method.

タイトル(別表記) Spatial analysis of Kawaguchi City crime data
フルテキストURL 13_017_022.pdf
著者 大下 優夫| 垂水 共之|
抄録 In this paper, we built some models of the spatial data, and evaluate those, using the crime data of Kawaguchi city, Saitama prefecture in Japan. Compute the Moran’I statistics of five crime data related to thefts in the city, the value of sneakthief take the aggregation. So, we pay attention to the sneak, and make a model to estimate the incidence of the events. As a regression, we select the old-age index among regional indexes. Applying a simple regression(SR), a spatial autoregressive model(SAR), a geographically weighted regression(GWR) , we evaluate these models. In GWR model, it is interesting that there are some sections in which the sign of the coefficient takes the opposite versus SR and SAR models. So, stratifying the data by the sign of it, we investigate to data precisely.

タイトル(別表記) Swap-Rate of Entrance Examination and Its Software -SRAS-
フルテキストURL 004_007_018.pdf
著者 垂水 共之| 山本 義郎|
抄録(別表記) When we select N₀ student from N applicants using a result of an entrance examination, which consists of two step selection, the primary test and the secondary test. It is important to evaluate the contribution for each test. Swap-rate is one of the measure of the contribution for each stage test, and it its widely used. In this paper, we describe a population swap-rate and a sample swap-rate in the first. Next, we consider the distribution of applicants who change the result of the test from pass to fail. Finary, we introduce our system "SRAS - Swap-Rate Analysis System-", that can analyze the examination data on such point of view.
