A note on the geometric structure of the t-distribution
조봉식,정선영 한국데이터정보과학회 2010 한국데이터정보과학회지 Vol.21 No.3
The Fisher information matrix plays a significant role in statistical inference in connection with estimation and properties of variance of estimators. In this paper, the parameter space of the t-distribution using its Fisher's matrix is defined. The alpha-scalar curvatures to parameter space are calculated.
A NOTE ON THE BIVARIATE PARETO DISTRIBUTION
조봉식,정선영 호남수학회 2013 호남수학학술지 Vol.35 No.1
The Fisher information matrix plays a signi cant role in statistical inference in connection with estimation and properties of variance of estimators. Using Bivariate Lomax distribution, we can define "statistical model" and drive the Fisher information matrix of Bivariate Lomax distribution. In this paper, we correct the wrong of the paper [7].
소집단 협동학습이 수학 학습 부진아의 학력신장에 미치는 효과 분석
조봉식,유재은 한국수학사학회 2002 Journal for history of mathematics Vol.15 No.2
The purpose of this paper is to analyze the the effect on the academic improvement, applying various teaching methods throughout cooperative teaming in small groups to inspire slow-learners'interest on mathematics and impove capability to solve problems and achievement degree of studies. The subject of the study is as follows: 1. What is the difference of students'interest on mathematics between cooperative learning in small groups and large group learning\ulcorner 2. Is there any difference of slow-learners' achievement degree of studies between cooperative learning in small groups and large group learning?

본 연구의 목적은 첫째, 실업계 고등학교 학생들의 학력 실태와 진로 희망, 수학에 대한 인식을 정확히 파악하고 둘째, 실업계 고등학교 학생들에게 적합한 여러 가지 수학 교수 방안을 찾아보고 셋째, 현행 실업계 고등학교 교육과정의 개선을 통하여 수학 학습의 효율성을 높일 수 있는 방안을 찾아보고자 한다. The purposes of this study are that understand vocational high school student's scholastic ability, dream and conception about mathematics exactly and that we find a educational mathematics program suitable to vocational high school student. Through this improvement of the curriculum in vocational high school, we will find the way that increase efficiency.
α-SCALAR CURVATURE OF THE t-MANIFOLD
조봉식,정선영 호남수학회 2011 호남수학학술지 Vol.33 No.4
The Fisher information matrix plays a signicant role in statistical inference in connection with estimation and properties of variance of estimators. In this paper, we define the parameter space of the t-manifold using its Fisher's matrix and characterize the t-manifold from the viewpoint of information geometry. The α-scalar curvatures to the t-manifold are calculated.

To investigate whether hypoalgesia in the depressives is a depression dependent pheno-menon or a trait, the authors measured pain threshold of 18 female depressives in-remis-sion and 8 controls. Pain threshold of the depressives in remission was significantly higher than that of the controls. From this result, the authors suggest that hypoalgesia in the depressives may be a given trait, rather than a phenomenon dependent on the state of depression.
