Question about minimum value for cdf

[elray1]

Looking at the schema for this line:

schemas/v4.0.0/tasks-schema.json

Line 941 in 47beca8

"minimum": 0

I'm not entirely sure what that minimum of 0 encodes -- is it saying that the output_type_ids for cdf model outputs must be at least 0 (if they are numeric)? If so, I think we should take that requirement out. Most disease forecasting systems would probably be set up with targets that are like "number of hospitalizations", in which case a minimum of 0 makes sense. But in principle, someone could have a different target like "change in number of hospitalizations", in which case negative values might be reasonable, corresponding to a decrease in hospitalizations.

Again, I'm not totally clear on what that entry is specifying, so please correct me if the above interpretation is wrong!

Yes your interpretation of the minimum is correct and indeed, if negative cdf output type IDs are possible, this should definitely be removed!
