This function tests independence in rxc contingency tables
ind_test_rc(M, threshold = 2, rounding = 3)
This function returns a vector with statistic of quadratic chi2 or inv chi2 corresponding to pvalue of Fisher test, p-value of quadratic chi2 test or Fisher test for low numbers, degree of freedom and test performed (Chi-square, Fisher or None).
is an r by c table of non-negative integers
is a threshold for low expected numbers; default is 2
is the level of rounding for outputs; default is 3
