        Weighted Dataset operations.

        Parameters
        ----------
        weights : DataArray
            An array of weights associated with the values in this Dataset.
            Each value in the data contributes to the reduction operation
            according to its associated weight.

        Notes
        -----
        ``weights`` must be a DataArray and cannot contain missing values.
        Missing values can be replaced by ``weights.fillna(0)``.
