Multiple Imputation of Missing Covariates in Randomized Controlled Trials
(2019)Baseline covariates in randomized experiments play a crucial role in the estimation of treatment effects. Random assignment ensures independence of the covariates and the treatment, which is essential for objective interpretation ... -
Testing Between Different Types of Poisson Mixtures with Applications to Neuroscience
(2019)We propose a hypothesis testing for different types of stochastic order of mixture distributions (PRML classifier) and a hypothesis testing for screening out data with mixture distributions (PRML filter), in a Bayesian ... -
The Impact of a Hostel on Outcomes for Pediatric Cancer Patients in Northern Tanzania
(2019)Background: There is a significant disparity in survival rates for pediatric cancer in low and middle-income countries compared to high-income countries. A variety of factors contribute to this disparity including late stage ... -
