title: [The use of the instrument for the control of statistic hypotheses for the analysis of patient population in mental hospitals].
abstract: To reveal homogeneous groups of old-age patients in psychiatric hospitals, a classic method of mathematical statistics chi 2 criterion of Pearson for the contingency tables was used. The general sample of patients (655 individuals) was from hospitals of Moscow (281 persons), Tver (250 individuals) and Kalyazin (124 patients). Description of the patients was made by means of sets including 44 signs from three blocks: demographic, social and clinical. The pattern of homogeneous and heterogeneous groups was presented for each separate sign that was quite important for practical activity of psychiatrists-gerontologists.
