Python implementation of Corrected Fisher Randomization (CFR)
Install:
pip install corrected-fisher-randomization
Usage example:
import numpy as np
import scipy.io
from corrected_fisher_randomization import CFR
model_dim = 10
data = scipy.io.loadmat('./exampleData.mat')
dataTensor = data['dataTensor']
print(dataTensor.shape)
t = data['t']
mask = np.logical_and(t > - 50, t < 350)
CFR(dataTensor, mask, model_dim)
The algorithm description can be found in the following article:
