- NDVar.sum(axis=None, **regions)
Compute the sum over given dimensions
axis (Union[None, str, Sequence[str], NDVar]) – Dimensions over which to operate. A str is used to specify a single dimension, a tuple of str to specify several dimensions, None to compute the sum over all dimensions. An boolean NDVar with the same dimensions as the data can be used to compute the sum in specific elements (if the data has a case dimension, the sum is computed for each case).
**regions – Regions over which to aggregate. For example, to get the sum between time=0.1 and time=0.2, use
name (str) – Name of the output NDVar (default is the current name).
The sum over specified dimensions. Return a Var if only the case dimension remains, and a float if the function collapses over all data.
