comp_stat {funStatTest}

Compute multiple statistics

Description

Computation of the different statistics defined in the package. See Smida et al (2022) for more details.

Usage

comp_stat(MatX, MatY, stat = c("mo", "med"))

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).

stat

character string or vector of character string, name of the statistics for which the p-values will be computed, among "mo", "med", "wmw", "hkr", "cff".

Details

For HKR statistics, only the values of the two statistics, namely HKR1 and HKR2 and not the eigen values (see stat_hkr() for more details).

Value

list of named numeric value corresponding to the statistic values listed in stat input.
