scvelo.utils.get_moments

scvelo.utils.get_moments(adata, layer=None, second_order=None, centered=True, mode='connectivities')

Computes moments for a specified layer.

First and second order moments. If centered, that corresponds to means and variances across nearest neighbors.

Parameters:

• adata (AnnData) – Annotated data matrix.

• layer (str (default: None)) – Key of layer with abundances to consider for moment computation.

• second_order (bool (default: None)) – Whether to compute second order moments from abundances.

• centered (bool (default: True)) – Whether to compute centered (=variance) or uncentered second order moments.

• mode (‘connectivities’ or ‘distances’ (default: ‘connectivities’)) – Distance metric to use for moment computation.

Returns:

Mx

Return type:

first or second order moments
