[Analysis of the geographic distribution of cancer incidence exemplified by lung tumors in East Germany for the period 1978-1982].
Analysing the regional distribution of cancer incidence a graphic presentation of the data in form of cancer maps often give a clear idea of the underlying distribution. Nevertheless, if the cancer map is variegated, an answer to the question of regional dependence of the incidence is difficult to find. Statistical methods as the test of Kemp et al. (3), which is based on the mean absolute difference in rank between all possible pairs of adjacent regions with a common border, or outlier tests can be helpful in such cases. An easy calculable approximation of Kemp's method will be presented and demonstrated on lung cancer incidence in districts of the GDR over the five-year period 1978-1982. Moreover statistical methods of generating new hypotheses about possible risk factors will be discussed.
