Zero-one inflated beta as "censored" beta?

[saudiwin]

Hi -

What might work better for you is a model I designed that is a simplified version of zero-one inflation. It’s particularly for situations where you don’t really care about the 0s and 1s, which seems like is your case. Also, you can fit this model with brms with mixed effects etc, and it should be more stable/easier to estimate. See the link here:

Hi Frank - Great question. I added a little info to an appendix about this as I think it is a pertinent question. I added the appendix to the Github here: https://github.com/saudiwin/ordbetareg/blob/master/kubinec_ord_betareg_appendix.pdf The cutpoints are weakly identified by the prior (i.e., the difference between them is Normally distributed), so it is really OK to fit a model with no observations at the bounds (or just one bound). It’s probably better to do so in the likely case that futu…
