Describe hurdle model, Advanced Statistics

Assignment Help:

Hurdle Model: The model for count data which postulates two processes, one generating the zeros in the data and one generating positive values. The binomial model decides the binary outcome of whether the count variable has a zero or the positive value. If the value is positive then the 'hurdle is crossed' and the conditional distribution of the positive values is a appropriate zero-truncated probability distribution.
