I am writing to you following one of the posts on GitHub (https://github.com/glmmTMB/glmmTMB/issues/355). I am trying to fit proportion data with lots of 0s and a few 1s into a hurdle model using glmmTMB. Is this possible? Would you have any example code please?

Thank you!

Hi Ben, Thanks for your reply. To fit hurdle model using glmmTMB, do you have any example code? will it still have the same issue? Actually i thought using the ziformula option is the way to fit hurdle model, but since it shows such errors of inappropriate values, i guess i may misse some options for hurdle model.
