BUG: masked mean unnecessarily overflowing by phofl · Pull Request #48378 · pandas-dev/pandas (original) (raw)

Ah, nice, this is possible now because we require numpy >= 1.20 (the where keyword was only added later to mean)

Do we want to add mean to the Masked Array interface (I would say yes, but want to check anyway)? This would simplify things a bit.

Yeah, I am not really sure why historically sum, prod, etc are methods, while mean is only handled inside _reduce
