Controlled branching processes (CBP) with a random control function provide a useful way to model generation sizes in population dynamics studies, where control on the growth of the population size is necessary at each generation. An important special case of this process is the well known...

This paper is concerned with a general approach for sequential estimation for dependent observations, and an application to a non-standard first order autoregressive process having Weibull errors. The natural estimator of the autoregressive parameter when the errors are non negative turns out to...
