Case-control association studies using unrelated cases and controls may suffer from potential confounding due to population stratification. Bias and variance distortion caused by population stratification in the commonly used allele-based tests can considerably inflate the Type I error rate. It...

Hidden population stratification (PS) is a main concern in the analysis of case-control genetic association studies. All methods to correct for hidden PS have been focused on classical hypothesis testing, and cannot be directly applied to Bayesian analysis. In this paper, to study the impact and...

After expressing the Fisher information in randomly censored data in terms of hazard rates, we examine the loss of Fisher information under the Koziol-Green random censoring model. Because the same parameter enters both the survival and censoring distributions in this model, the censored data...
