ott.geometry.geodesic.Geodesic.std_cost_matrix

property Geodesic.std_cost_matrix: float

Standard deviation of all values stored in cost_matrix.

Uses the apply_square_cost() to remain applicable to low-rank matrices, through the formula:

\[\sigma^2=\frac{1}{nm}\left(\sum_{ij} C_{ij}^2 - (\sum_{ij}C_ij)^2\right).\]

to output \(\sigma\).
