Evaluating Imputation Methods to Improve Prediction Accuracy for an HIV Study in Uganda Open
Standard statistical analyses often exclude incomplete observations, which can be particularly problematic when predicting rare outcomes, such as HIV positivity. In the linkage to the HIV care dataset, there were initially 553 complete HIV…

A note on point estimation and interval estimation of the relative treatment effect under a simple crossover design Open
To increase power or reduce the number of patients needed for a parallel groups design, the crossover design has been often used to study treatments for noncurable chronic diseases. However, in the presence of carry‐over effect caused by t…
