title: A stochastic diffusion model of the time path of nuptiality.
abstract: "The time path of nuptiality is approximated by means of the log normal diffusion process.  The drift coefficient is estimated by the method of maximum likelihood.  Swedish and Canadian data on nuptiality have been utilised to illustrate the model.  A piece-wise fitting of the log-normal model to the Swedish data reveals that the drift coefficient is changing over time.  The use of mixing distribution is suggested to remedy this problem.  On the whole the Hajnal theory of nuptiality transition is supported.  It is also seen that the Hajnal transition is one in a series of transitions."
