    Implementation of a Parallel Algorithm to Simulate the Type I Error Probability by Francisco Novoa-Muñoz

    Published 2024-05-01
    “…Therefore, this article analyzes the performance of two parallel implementations (<i>parRapply</i> and <i>boot</i>) which significantly reduce the execution time of simulations of type I error probability for a goodness-of-fit test for the bivariate Poisson distribution. The results obtained demonstrate how the parallelization strategies accelerate the simulations, reducing the time by 50% to 90% when using 2 to 12 processors running in parallel. …”

    Estimating transmission heterogeneity and case ascertainment from variations in case counts in surveillance data by Dr Judith Bouman, Dr Jantien Backer, Dr Christian Althaus

    Published 2025-03-01
    “…Results: Assuming a constant observation probability, we showed that the daily numbers of reported cases in surveillance data are expected to follow a quasi Poisson distribution. The overdispersion in reported cases is a function of the expected number of cases, the effective reproduction number, the overdispersion in secondary cases k, and the observation probability. …”

    Trends in catch rates of sawfish on the Australian North West Shelf by AV Harry, CB Wakefield, SJ Newman, JM Braccini

    Published 2024-02-01
    “…To standardize catch rates and account for excess zeros in the data, we employed generalized additive models for location, scale, and shape (GAMLSSs) using a zero-inflated Poisson distribution. For green sawfish, catch rates approximately doubled over the study period, while an oscillating trend was observed for narrow sawfish catch rates. …”
