Models with time-varying predictors for meningitis in Navrongo, Ghana

英文摘要：

The "meningitis belt" is a region in sub-Saharan Africa where annual outbreaks of meningitis occur, with large epidemics observed cyclically. While we know that meningitis is heavily dependent on seasonal trends (in particular, weather), the exact pathways for contracting the disease are not fully understood and warrant further investigation. This manuscript examines meningitis trends in the context of survival analysis, quantifying underlying seasonal patterns in meningitis rates through the hazard rate for the population of Navrongo, Ghana. We compare three candidate models: the commonly used Poisson generalized linear model, the Bayesian multi-resolution hazard model, and the Poisson generalized additive model. We compare the accuracy and robustness of the models through the bias, RMSE, and the standard deviation. We provide a detailed case study of meningitis patterns for data collected in Navrongo, Ghana.
