Adjusting for overdispersion in piecewise exponential regression models to estimate excess mortality rate in population-based research
Abstract Background In population-based cancer research, piecewise exponential regression models are used to derive adjusted estimates of excess mortality due to cancer using the Poisson generalized linear modelling framework. However, the assumption that the conditional mean and variance of the rat...
