Presented are models for length of hospital stay data. The Hurdle model is an extension to the Poisson model when the data structure can be considered as two separate processes as was evident with the present case study. Hospital data was considered and collected as part of a larger study over a five year period. The Hurdle model appeared the most appropriate in terms of overall goodness of fit.
