Estimation of a preference matrix for women's choice of male sexual partner according to rate of partner change, using partner notification data.

Data from a study of partner notification for venereal chlamydial infection are used to estimate the contact preference matrix, according to sexual contact activity levels of the male partners, of young heterosexual women. A method for correcting data for the bias introduced by studying infected women only is presented. Results indicate that an overall proportional mixing model is not an adequate description of the mixing pattern.
