energymethod - Two-Sample Test of many Functional Means using the Energy Method
Given two samples of size n_1 and n_2 from a data set
where each sample consists of K functional observations
(channels), each recorded on T grid points, the function energy
method implements a hypothesis test of equality of channel-wise
mean at each channel using the bootstrapped distribution of
maximum energy to control family wise error. The function
energy_method_complex accomodates complex valued functional
observations.
