So i’m trying to use Arviz.compare to visually compare some fitting.
For each model, some different data sets can be fitted, so i’m trying to compare only data sets shared by all models.
With this, I have the pointwise ELPD data from each model, which I thought I could pass onto Arviz.compare (arviz.compare — ArviZ dev documentation) as the API guide states it can take ELPD data.
However, it throws this error:
I was wondering if I’m misunderstanding the API guide, or how arviz.compare works - can anyone help?
