Tidymodels Support for Beta Regression #903

Open nrjenkins opened 1 year ago

nrjenkins commented 1 year ago

Are there any plans to add support for Beta regression in Tidymodels? The Beta distribution is the ideal choice when trying to model rates or proportions, but the only options for modeling these data are linear regression (normal distribution) or binomial regression (logit/probit).

Thanks!

Hello @nrjenkins 👋 thanks for the feature request, i have moved this issue to the {parsnip} package as it would likely be added to this package or one of its extension packages. Likewise, we have a larger thread at https://github.com/tidymodels/parsnip/issues/35 about future models.

Just chiming in to say that I too would find a lot of value in this being added to the parsnip package or an extension package.

@ttrodrigz Do you have a recommendation for an engine for beta regression? I'm aware of betareg and spot gamlss being listed in the Econometrics Task View.

ttrodrigz commented 4 months ago

Hi @hfrick, those are the only two that I am aware of as well, and only have experience using betareg.
