| Sumario: | The writers present a mixture model in which logistic regression and piecewise proportional hazards models are combined for analysis of duration data. They state that the model permits simultaneous estimation of two sets of effects of covariates—one of the probability of an event and the other of the timing of that event. They demonstrate the application of the model by means of an investigation of the effects of women's characteristics and of the acceptance of a one-child certificate on the birth of second children in China. Their analysis indicates that both factors influence the probability of having a second child but that only the acceptance of a one-child certificate has a significant and strong impact on the second-birth interval. |
