G-Square test
Perform an independence test using G-Square test 1. This test is based on the log likelihood ratio test.
Usage
from causallearn.utils.cit import gsq
p = gsq(data, X, Y, conditioning_set)
Parameters
data: numpy.ndarray, shape (n_samples, n_features). Data, where n_samples is the number of samples and n_features is the number of features.
X, Y and condition_set: column indices of data.
G_sq: True means using G-Square test; False means using Chi-Square test.
Returns
p: the p-value of the test
