I noticed that when
vcov fails, it returns a Pumas.PumasFailedCovariance object instead of erroring. Can a user do anything with that object? I was expecting it to error, based on how Pumas behaves when
infer and so forth fail, so I had written the
vcov into a try/catch for a large simulation project before realizing that try/catch doesn’t work b/c of this Pumas quirk.
