a three-day introductory workshop to multilevel modelling using MLwiN will take place If you plan to run any workshops using MLwiN, please notify Amy Burch and she will advertise these workshops on the multilevel web site. In the standard multilevel model lower level units are uniquely classified within one higher level unit, for example students within schools or people within households. In m...

Generalized linear mixed models (GLMM) form a very general class of random effects models for discrete and continuous responses in the exponential family. They are useful in a variety of applications. The traditional likelihood approach for GLMM usually involves high dimensional integrations which are computationally intensive. In this work, we investigate the case of binary outcomes analyzed u...

In meta-analysis, between-study heterogeneity indicates the presence of effect-modifiers and has implications for the interpretation of results in cost-effectiveness analysis and decision making. A distinction is usually made between true variability in treatment effects due to variation in patient populations or settings and biases related to the way in which trials were conducted. Variability...

Anemia is a major public health problem in Africa, affecting an increasing number of children under five years. Guinea one the most affected countries. In 2018, prevalence rate was 75% for This study sought to identify factors associated with anemia and map spatial variation across eight (8) regions years, which can provide guidance control programs reduction disease. Data from Multiple Indicat...

We propose a sampling-based Bayesian t test that allows researchers to quantify the statistical evidence in favor of the null hypothesis. This Savage-Dickey (SD) t test is inspired by the Jeffreys-Zellner-Siow (JZS) t test recently proposed by Rouder, Speckman, Sun, Morey, and Iverson (2009). The SD test retains the key concepts of the JZS test but is applicable to a wider range of statistical ...

Dihydroartemisinin (DHA) is an active metabolite of artesunate (ARTS) and is highly effective in the treatment of malaria, a life threatening parasitic disease. ARTS causes rapid reduction in parasitemia and fever in patients with falciparum malaria and is associated with a radical cure rate of (> 90%) if administered for a period of 5-7 days. A phase I single oral dose escalation study in heal...
