| Abstract: | A number of techniques useful in describing and modeling social processes are detailed. Emphasis is placed on the analysis of changes in categorical variables as they occur in continuous time. The procedures considered are mainly non-parametric, although parametric alternatives do exist when the appropriate distributional assumptions are met. Specifically, life tables and proportional hazards models are discussed and illustrated through an analysis of first live birth intervals for a sample of white American women. The generality of proportional hazards models is outlined by considering extensions of the basic model to include competing risks, time-dependent covariates, and repeatable events. |
