Bayesian inference for a record value statistics(RVS) model of nonhomogeneous Poisson process is considered. We seal with Bayesian inference for double exponential, Gamma, Rayleigh, Gumble RVS models using Gibbs sampling and Metropolis algorithm and also explore Bayesian computation and model selection.

In this paper, we discuss simple ways of implementing non-basic kernel density estimators which typically ceed extra pilot estimation. The methods utilize order statistics at the pilot estimation stages. We focus mainly on bariable lacation and scale kernel density estimator (Jones, Hu and McKay, 1994), but the same idea can be applied to other methods too.

The statistics of traditional korean medicine is essential aspects for the information based policy establishment and the evidence based traditional korean medicine research. But because the integrated statistics service of traditional korean medicine is not provided, people are hard to find out suitable statistics. Thus we analyzed the produced statistics from many ministries, classified it into 7 categories and extracted common fields from it. We designed the database schema by summary table dynamic production method from the analysis of statistics and designed the system composed of excel import, statistics analysis, chart creation and search engine. Finally we implemented the statistics system of traditional korean medicine which users are capable of modifying the statistics data freely. We hope that the implemented system will provide pliability in searching and finding statistical information.

Pain is subjective, while statistics related to pain research are objective. This review was written to help researchers involved in pain research make statistical decisions. The main issues are related with the level of scales that are often used in pain research, the choice of statistical methods between parametric or nonparametric statistics, and problems which arise from repeated measurements. In the field of pain research, parametric statistics used to be applied in an erroneous way. This is closely related with the scales of data and repeated measurements. The level of scales includes nominal, ordinal, interval, and ratio scales. The level of scales affects the choice of statistics between parametric or non-parametric methods. In the field of pain research, the most frequently used pain assessment scale is the ordinal scale, which would include the visual analogue scale (VAS). There used to be another view, however, which considered the VAS to be an interval or ratio scale, so that the usage of parametric statistics would be accepted practically in some cases. Repeated measurements of the same subjects always complicates statistics. It means that measurements inevitably have correlations between each other, and would preclude the application of one-way ANOVA in which independence between the measurements is necessary. Repeated measures of ANOVA (RMANOVA), however, would permit the comparison between the correlated measurements as long as the condition of sphericity assumption is satisfied. Conclusively, parametric statistical methods should be used only when the assumptions of parametric statistics, such as normality and sphericity, are established.

The role of the department of statistics in Korea is discussed. There are more than 70 statistics departments in the universities throughout the country. However, we can hardly find that statisticians and statistical service organizations who are responsible for, for example, identifying the statistical services needed by clients in our society. In developed countries, statistics is now widely employed in all areas of societies including industry and government. Statistics and statisticians also have vital internal roles in production, research, marketing, and support functions of the modern corporation as stated by Marquardt(1987). Professors in the department of statistics are responsible for solving the problems with the discipline of statistics and with statisticians. In this article some of those problems are explored.

Library statistics is used for internal decisions to know and assess library operations or for external justifications to show of how libraries meet users' needs and contribute to the organization. It is included same frameworks with social indicators and cultural indicators in national level. In this basis, national library statistics, they are ANSI/NISO Z39.7, Canada's Core library statistics, LIST of united Kingdom, are examined and Delphi method is used for new scheme of korean library statistics. As the results, it is suggested that new korean framework of library statistics is composed of 7 parts with 31 items. There are 6 parts with 21 items of social indicators or cultural indicators related to library items as well.

Statistics is based on a data, therefore a practical use of suitable data is important in teaching statistics. But, most teachers feel always that there is seldom data that students can understand easily. In this study, we presented a teaching method of statistics education that can elevate student's participation and interest in their statistics class using a web-based data collection program and MS Excel software. Also, the presented teaching method may apply extending to various part of statistics education.

Purpose - This study measures how competitive securities broker-dealers are in the Korean financial markets. It aims to test whether the markets are perfectly competitive or monopolistic since the global financial crisis of 2008. Research design, data, and methodology - We apply the method developed by Panzar and Rosse (1987), H-statistics, which offers an index for the competitiveness as well as statistical tests. The dataset in use is retrieved mainly from the quarterly statements of the financial services companies by the Financial Statistics Information System of the Financial Supervisory Service. General information on officers and employees is utilized in addition to balance sheets and income statements of securities companies. Results - H-statistics for 2009-2015 is about 0.7 that is a robust estimate regardless of model specifications such as full trans-log, partial trans-log, and Cobb-Douglas regression equations. H-statistics for each year is also computed in similar ways in that it varies between 0.3 and 0.9. Conclusions - Since the global financial crisis, H-statistics concludes that securities broker-dealer markets in Korea is neither perfectly competitive nor monopolistic. It evidences that the markets are rather monopolistically competitive. The trend in annual H-statistics leads to the same conclusion but the result is not such stable that overall H-statistics implies.
