[Feature request]: Allow Mixed models to only estimate the random effects. #2780

Closed qymera0 closed 1 week ago

qymera0 commented 1 week ago

Description

It would be interesting if we could specify a mixed model with only random effects. In Engineering and Industrial Statistics, this is a very common case, where you want to just estimate a process variance, but no systematic effect is present.

Purpose

Increase the flexibility of different model structures.

Use-case

Describe the solution you would like

Allow specify the models like this: y ~ 1 + (1 | z)

Describe alternatives that you have considered

I tried to manually change the formula at R console, but when I hit ctrl + enter, it gives me an error.

Additional context

This case can be complementary of the feature request I did related to add nested random terms.
