Experience in the use of correlation analysis for evaluating the synchronism of changes in infectious morbidity rate on different territories

摘要

The possibility of using correlation analysis for evaluating the synchronism of changes in infectious morbidity rate on different territories was studied. The study demonstrated that the intensity of correlative relationships was mainly influenced by the degree of manifestation and the direction of prolonged tendencies in the changes of infectious morbidity on the territories under study. The presence of prolonged pronounced tendencies towards growth or decrease in the compared curves characterizing prolonged morbidity dynamics was found to limit the use of correlation analysis for the evaluation of synchronism of changes in morbidity rate.
