Thanks for finding that @sjvrijn

I don't have a view on what we should use, so I would vote to defer to numpy (and pandas, which also seems to use 1), referencing that documentation to the extent xarray isn't changing anything.

But others probably have a stronger view on which ddof we should use?

Good question. Setting ddof should work. It's passed on to nanvar from NumPy or bottleneck, both of which default to ddof=0.
