Don't compute variables for years we haven't implemented yet #934

Open MaxGhenis opened 2 years ago

MaxGhenis commented 2 years ago

Currently you can specify years we haven't implemented for many tax and benefit programs. I think the simplest way to avoid this is to replace def formula with def formula_2021 or whatever the first year we have that's vetted. It's also possible to return NaNs.

Thanks @martinholmer for the tip.

Yes, I'd favour setting the default value to np.nan (with a constant named NULL or something), and using dated formulas.
