Model selection and bayes estimates of the parameter for distribution of waiting time to first birth

This paper considers various models for first birth interval to a married woman with an aim to pick up a model which is best fit. For fitting the various models, the Bayes estimates of the parameters involved in the models are obtained using WinBUGS based on the Markov Chain Monte Carlo technique. The comparison of the models regarding their fitness is made on the basis of DIC criterion. The data used in the present study is taken from National Family Health Survey III Uttar Pradesh.
