Tests of independence in contingency tables
Gažová, Miroslava ; Omelka, Marek (advisor) ; Vávra, Jan (referee)
This thesis deals with the problem of independence testing between two discrete ran- dom variables. At first, we define contingency table and the basic notations in the context of independence tests. We describe the most commonly used tests in this field. Next, we present the U-statistics Permutation test of independence (USP), which was first presen- ted by authors T.B.Berrett and R.J.Samworth (2021). In the next section, we focus in better detail on fourfold contingency tables and corresponding problem of testing for the equality of parameters from two independent binomial distributions. In the end, we apply the tests on the real data using the R enviroment. 1
