A hurdle model is a class of statistical models where a random variable is modelled using two parts, the first which is the probability of attaining value 0, and the second part models the probability of the non-zero values. The use of hurdle models are often motivated by an excess of zero's in the data, that is not sufficiently accounted for in more standard statistical models. In a hurdle model, a random variable x is modelled as WebDouble hurdle model Extensions Cragg Estimation Jones Estimation Cragg’s formulation Model Cragg (1971) proposed the extension that the probability of a zero realisation, 1 −Φ(.), is not directly to the density for a continuous realisation, φ(.), but instead governed by some other process yi = y∗ i = xiβ +ε1i if xiβ +ε1i > 0 and ...
