| Research Abstract |
(1). The objects of this project are (A) to study theory and methods on nonlinear statistics by the head investigator and the investigators and (B) to hold meetings on topics of nonlinear statistics in order to have discussion with each other and with researchers outside our group.
(2). On (A), the head and the investigators studied several topics. Many of them are published in several scientific journals or presented at domestic/international meetings. The details of them are listed in the written report and some selected works are at references of this report.
(3). On (B), we held meetings seven times. The titles of our meetings are as followes.
(1). First meeting on nonlinear statistical models and its applications at Kure.
(2). Second meeting on nonlinear statistical models and its applications at Oita.
(3) Meeting on nonlinear problem and experimental design at Hiroshima University.
(4) Meeting on nonparametrics, nonlinear models and simulation at Seikei University.
(5) Meeting on nonlinear statistical models and data analysis at Toba.
(6) Meeting on nonlinear statistical models and computer at Kanazawa University.
(7) Meeting on experiment data and nonlinear statistical models at Matsuyama.
The topics presented at these meetings are from theoretical statistics to analysis of practical data having nonlinear structure. Some of them are on established results and some are on unsolved problems. Most of them are on computer intensive methods such as neural networks, determination of smoothing parameter and computation points on spline regression analysis, generation of random numbers, growth curve model, nonlinear models at medical statistics, statistical graphics and so on.
