conformal prediction methods for `fable` & `fabletools`?

[frankiethull]

hi @mitchelloharawild -

Related to a similar expansion in the forecast framework, conformalForecast, is there any chance conformal methods will be added to the tidyverts universe?

I use fable and share it regularly with R programmers. Using tsibbles instead of ts objects makes it super friendly. While I can leverage conformalForecast, would love to see conformal methods in fable since it jives so well with the tidyverse.

Maybe @xqnwang can write a fable extension package to do this.
