This function tests independence in rxc contingency tables
ind_test_rc(M, threshold = 2, rounding = 3)
M | is an r by c table of non-negative integers |
---|---|
threshold | is a threshold for low expected numbers; default is 2 |
rounding | is the level of rounding for outputs; default is 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).
