stat_mo {funStatTest}

MO median statistic

Description

The MO median statistics defined in Smida et al (2022) is computed to compare two sets of functional trajectories.

Usage

stat_mo(MatX, MatY)

Arguments

MatX

numeric matrix of dimension ⁠n_point x n⁠ containing n trajectories (in columns) of size n_point (in rows).

MatY

numeric matrix of dimension ⁠n_point x m⁠ containing m trajectories (in columns) of size n_point (in rows).

Value

numeric value corresponding to the MO median statistic value
