Implementation of a double-hurdle model
Witryna15 lut 2024 · The double hurdle is an extension of the standard censored regression (Tobit) model for limited dependent variables that allows the process that generates zero (censored) observations to be different from that which generates positive (uncensored) observations. Extensions of the hurdle model to count data and to panel data are … WitrynaThe dhreg command implements maximum likelihood estimation of the double-hurdle model for continuously distributed outcomes. The command includes the option to fit a p-tobit model, that is, a model that estimates only an intercept for the hurdle equation. The bootdhreg command (the bootstrap version of dhreg) may be convenient if the data ...

View history. Tools. 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 ...
