Table 4.
Estimated coefficients and standard errors for hazards models of contraceptive abandonment in 2011. The results for a standard model and a multiprocess model, modelling method choice and discontinuation conjointly, are compared. In the multiprocess model, IUD/Implants are not considered due to the limitations of the aML software and only the results of the hazard model part are shown
