6 авг. 2015 г. · I want to check the method of combining the results of these 2 models, in order to generate quantitative predictions (ultimately with CI).

14 янв. 2021 г. · I am using hurdle models to predict a continuous cost variable that has many exact zeros. I have fitted a hurdle model with a binomial component and a gamma ...

31 янв. 2023 г. · I fit a gamma hurdle model to invertebrate biomass data and am having trouble predicting from the model. I've been using these posts extensively to try to set ...

18 июл. 2020 г. · I am trying to use hurdle gamma model for one of my use cases, to handle a zero-inflated scenario. I have a very simple code creating dummy data with quite a ...

29 сент. 2013 г. · I'm trying to use a zero-inflated gamma model (or a gamma 'hurdle' model). The model is a mixture of logistic regression and generalized linear modeling.

16 янв. 2021 г. · How do I compare these models to choose between them? The Tweedie model indicates that the variable "disease" is strongly predictive of costs.

1 авг. 2020 г. · I am running a hurdle model using the glmmTMB function. My dependent variable is continuous and >= 0. I was looking for a function that would allow me to model ...

27 июл. 2022 г. · I would like to generate random data for a distribution which takes the form of hurdle-like model. Let's denote a random variable X with ...

28 апр. 2024 г. · I am using the pscl package in R to fit the hurdle model for count data (default specification: binomial for zero hurdle part and Poisson for ...

23 июл. 2019 г. · You can also make your own hurdle model by perform a binary regression on 0 vs. not 0, and then among the not zeros fit a zero-truncated model.
