Selected effects of age, height, and body mass on log odds of browsing and writing in conventional models for men and women (n = 1,855 users; estimates based on 1,147,499 browsing and writing observations). A and B show the log odds of women (A) browsing or (B) writing a potential mate as a function of age. C and D show the log odds of a women (C) browsing or (D) writing a potential mate as a function of height. E and F show the log odds of men (E) browsing or (F) writing a potential mate as a function of body mass. In all cases, the two stages of the mate choice process, browsing and writing conditional on browsing, are modeled separately. Nonlinearities in response to age, height, and body mass are represented by a cubic specification. Colors denote latent classes consistent within stage (browsing and writing) but not across them.
