  • For the two groups data from multivariate binomial distribution, we consider a bootstrap approach to inferring the simultaneous confidence level and its standard error of a collection of the dependent confidence intervals for the difference of proportions with an experimentwise error rate at the a level are presented. The bootstrap method is used to estimate the simultaneous confidence probability for the difference of proportions.

  • In this paper, multivariate discrete distribution is dealt with, where a set of r distinct counts are misreported as another set of r counts. First, the variance for the one variable marginal case is expressed in the form of an inverted parabola. Next, for the multivariate negative binomial case, elements of the covariance matrix are evaluated with reference to asymptotic distributions. Finally, for the same case of multivariate negative binomial, Bayesian estimates of the parameters and of the modification rates are provided.

  • In this paper, we consider simultaneous confidence intervals for the difference of proportions between two groups taken from multivariate binomial distributions in a nonparametric way. We briefly discuss the construction of simultaneous confidence intervals using the method of adjusting the p-values in multiple tests. The features of bootstrap simultaneous confidence intervals using non-pooled samples are presented. We also compute confidence intervals from the adjusted p-values of multiple tests in the Westfall (1985) style based on a pooled sample. The average coverage probabilities of the bootstrap simultaneous confidence intervals are compared with those of the Bonferroni simultaneous confidence intervals and the Sidak simultaneous confidence intervals. Finally, we give an example that shows how the proposed bootstrap simultaneous confidence intervals can be utilized through data analysis.

  • 우리는 자명하지 않은 상관 구조를 갖는 복잡한 다변량 자료에 직면하는 경우가 있다. 예를 들어 군집 구조 자료의 경우 생략된 변수들이 한 개 이상의 관측값에 동시적으로 영향을 줄 수 있기 때문에 결과들 간에 상관 구조를 모형화하는 것은 추정량의 효율성과 정확한 표준오차의 계산 등의 타당한 추론을 위해서 중요하다 관측값들 간에 종속성을 두는 표준 방법으로는 관측 값들이 관찰되지 않은 어떤 변수를 공유한다고 가정하는 것인데, 이러한 가정에 대해 본 연구에서는 다수준 모형을 고려한 상관된 임의효과 모형을 적합시켰다. 추정은 준모수적 접근방법으로 임의계수 분포에 대한 모수적 가정 없이 유한혼합 EM-알고리즘을 통하여 수행되었다.
