摘要:Bayesian approach to mixture models makes use of Gibbs sampler, the most common of Markov Chain Monte Carlo (MCMC), for estimation of posterior density and subsequent classification of objects into components of mixture, especially for conjugate priors. In practice conjugacy may ...

摘要:Sample size consideration is important in statistical analysis to ensure a given power of the test being applied. However, non-response of any nature may arise so that complete information is obtained from a subset resulting in an effective sample size smaller than desired. This,...

摘要:In this paper, we examined a test statistic for testing ordered alternative hypothesis under unequal group variances. The proposed modified t – test statistic obtained by replacing the pooled sample variance with the corresponding harmonic mean of variances in other to avoid...
