A Technique for Analyzing Some Factors Affecting the Incidence of Syphilis

In interpreting rates of syphilis incidence, it is worthwhile to evaluate certain factors which influence the probability of acquiring syphilis. In the past, these factors have been estimated separately either by graphical or by elementary numerical methods. A model is proposed in the present paper to measure these factors simultaneously. The parameters in the model can be estimated by multiple regression and tested for statistical significance.
