cumsum
(axis=0, *args, **kwargs)[source]¶ Cumulative sum of non-NA/null values.
When performing the cumulative summation, any non-NA/null values will be skipped. The resulting SparseArray will preserve the locations of NaN values, but the fill value will be np.nan regardless.
Parameters: - axis : int or None
Axis over which to perform the cumulative summation. If None, perform cumulative summation over flattened array.
Returns: - cumsum : SparseArray
