“…Subtil et al investigated whether water precautions reduce the rate of ear diseases [33]. Sanchez et al measured the impact of 4 weeks of daily swimming on rates of ear discharge with a tympanic membrane perforation and on the middle ear, and found swimming not to be associated with increased risk of ear disease [34]. Count data, for example in ear disease, usually contains too many or too few zeros and exhibits dispersion characteristics meanwhile.…”

For count data, though a zero-inflated model can work perfectly well with an excess of zeroes and the generalized Poisson model can tackle over- or under-dispersion, most models cannot simultaneously deal with both zero-inflated or zero-deflated data and over- or under-dispersion. Ear diseases are important in healthcare, and falls into this kind of count data. This paper introduces a generalized Poisson Hurdle model that work with count data of both too many/few zeroes and a sample variance not equal to the mean. To estimate parameters, we use the generalized method of moments. In addition, the asymptotic normality and efficiency of these estimators are established. Moreover, this model is applied to ear disease using data gained from the New South Wales Health Research Council in 1990. This model performs better than both the generalized Poisson model and the Hurdle model.
