Module aggregate 

Block and weighted aggregation: coarsen, weighted_sum, weighted_mean, dot.

Enums

CoarsenBoundary

What coarsen does when a dimension is not a multiple of its window.

Functions

coarsen

Reduce non-overlapping blocks, like xarray.DataArray.coarsen.

dot

Sum of products over the named shared dimensions, like xarray.dot.

weighted_mean

Weighted mean over axes, like xarray.DataArray.weighted(w).mean(). Weights of null values do not count. The result is floating point.

weighted_sum

Weighted sum over axes, like xarray.DataArray.weighted(w).sum(). Null values of a count as zero. Result type follows a * weights.
