“…The popularity of the Cox models, in part, stems from their flexibility; that is, they do not require an initial hazard function, unlike the rival parametric models which assume a certain shape for the hazard function (Cox, 1972). 2 Cox models have extensively been used in criminological research, including family violence (Stansfield & Williams, 2014), racial differences (Jung et al, 2010), teen court process (Rasmussen, 2004), and sex offenders (Rice & Harris, 1997). Most recently, Wolff , Baglivio, Piquero, Vaughn et al (2015) examined the effects of adverse childhood experiences on the time between completion of a community-based juvenile justice service and re-arrest among a statewide sample of juvenile offenders in Florida.…”
