The Analysis of the Influence of Residence in the Purchase of Pharmaceutical Products

This paper analyzes the relationship between the purchase of pharmaceutical products in pharmacies and the residence of customers. The customers sampled lived in either a city or in a village. The first step in this paper was to statistically detect the differences between residence of a town and a village whiles the second step aimed at detecting the probability of purchase by residents of a city and residents of a village. Regression analysis, specifically logistic regression is used because the dependent variable is binary in nature. The analysis is conducted for five groups of medicaments: (1) medicines for immune support, (2) pharmacy cosmetics, (3) vitamins and minerals, (4) medicines to support the nervous system and (5) painkillers.
