Tests for Connection Between Clustering of Polish Counties and Province Structure
Tests for Connection Between Clustering of Polish Counties and Province Structure

Summary/Abstract: The general idea of statistical tests which allow testing the influence of geographical or administrative units of upper level on clustering results of lower level units is presented, basing on the authors' earlier works. The so-called “active border” notion is used in these methods. If two counties (powiats) have been classified into different clusters then the border between them is called active. This border can be also the border between provinces. The number and length of active borders are used in the proposed test statistics. Their distribution depends on the actual geographic division of a given country. In this paper we present results for Poland and division for provinces and counties. Tables for test critical values and the approximation functions are given.
