A hurdle model is a class of statistical models where a random variable is modelled using two parts, the first of which is the probability of attaining the value 0, and the second part models the probability of the non-zero values. The use of hurdle models is often motivated by an excess of zeroes in the data that is not sufficiently accounted ...
Data with such an excess of zero counts are described as Zero-inflated. [4] Example histograms of zero-inflated Poisson distributions with mean of 5 or 10 and proportion of zero inflation of 0.2 or 0.5 are shown below, based on the R program ZeroInflPoiDistPlots.R from Bilder and Laughlin. [1]
In statistics, a tobit model is any of a class of regression models in which the observed range of the dependent variable is censored in some way. [1] The term was coined by Arthur Goldberger in reference to James Tobin, [2] [a] who developed the model in 1958 to mitigate the problem of zero-inflated data for observations of household expenditure on durable goods.
