Description
Hi,
I'm trying to generate paths using a theta model such that I can derive confidence intervals around an annual prediction based on monthly forecasts (as explained in https://otexts.com/fpp3/aggregates.html). However, I receive the following message :
Erreur dans UseMethod("generate") :
pas de méthode pour 'generate' applicable pour un objet de classe "fable_theta"
Is it simply because the implementation is forthcoming or is it impossible to do from a theta model? If the former, is there a way I could generate the output in the meantime?
Thanks a lot,
Polly

Research direction
Start by tracing the generate() entry point for objects of class fable_theta and the existing theta-model implementation. Check whether path generation is supported for this model and how the requested monthly-to-annual confidence intervals should be represented. Done means the intended theta-model output can be generated, with coverage confirmed by an appropriate test.
