Mixtures of prior distributions for predictive Bayesian sample size calculations in clinical trials.
28 Jul 2009 
In this paper we propose a predictive Bayesian approach to sample size determination (SSD) and re-estimation in clinical trials, in the presence of multiple sources of prior information. The method we suggest is based on the use of mixtures of prior ...

Two-dimensional semiparametric density ratio modeling of testicular germ cell data.
18 Jul 2009 Bivariate semiparametric inference based on a two-dimensional density ratio model is discussed and applied in testing the significance of risk factors regarding testicular germ cell tumors. The results from the joint analysis of height and weight ...

Regression modeling of combined data from multiple sample surveys.
18 Jul 2009 Combined data from multiple sample surveys are often used in population-based epidemiologic studies. Combining data can be beneficial in that sampling errors are reduced and coverage biases are corrected. Also, it is often necessary in order to use ...

18 Jul 2009 Multi-state models of chronic disease are becoming increasingly important in medical research to describe the progression of complicated diseases. However, studies seldom observe health outcomes over long time periods. Therefore, current clinical ...

18 Jul 2009 Data can arise as a length-biased sample rather than as a random sample; e.g. a sample of patients in hospitals or of network cable lines (experimental units with longer stays or longer lines have greater likelihoods of being sampled). The ...

A new generalization of Weibull distribution with application to a breast cancer data set.
18 Jul 2009 In this article, we propose a new generalization of the Weibull distribution, which incorporates the exponentiated Weibull distribution introduced by Mudholkar and Srivastava (IEEE Trans. Reliab. 1993; 42:299-302) as a special case. We refer to the ...

Student t-tests for potentially abnormal data.
18 Jul 2009 When the one-sample or two-sample t-test is either taught in the class room or applied in practice to small samples, there is considerable divergence of opinion as to whether or not the inferences drawn are valid. Many point to the 'Robustness' of ...

PURPOSE: The Retinoic Acid Receptor Alpha (RARA) gene is a potential candidate gene for myopia due to its differential expression in animal models during experimentally induced myopia. To test for whether RARA is associated with myopia we have ...

12 Jul 2009 Sugarcane breeders in Australia combine data across four selection programs to obtain estimates of breeding value for parents. When these data are combined with full pedigree information back to founding parents, computing limitations mean it is not ...
