BirthDeathProblem.push(data=None, subset=None, normalize=True, *, split_mass=False, scale_by_marginals=False)¶

Push data through the transport_matrix.

Parameters:

data (Union[str, ndarray[tuple[int, ...], dtype[floating]], Array, None]) –
Data to push through the transport matrix. Valid options are:
- ndarray - array of shape [n,] or [n, d].
- str - key in adata_src.obs['{data}']. If subset is a list, the data will be a boolean mask determined by the subset. Useful for categorical data.
- None - the value depends on the subset.
  - list - names in adata_src.obs_names to push.
  - tuple - start and offset indices \((subset[0], subset[0] + subset[1])\). that define a boolean mask to push.
  - None - uniform array of \(1\).
subset (Union[str, List[str], Tuple[int, int], None]) – Push values contained only within the subset.
normalize (bool) – Whether to normalize the columns of data to sum to \(1\).
split_mass (bool) – Whether to split non-zero values in data into separate columns.
scale_by_marginals (bool) – Whether to scale by the source :term`marginals` a.

Return type:

Returns:

: The transported values, array of shape [m, d].
