Branching Processes provide appropriate mathematical models for description of the probabilistic evolution of systems whose components (cells, particles, individuals in general), after a certain life period, reproduce and die. In particular, a controlled branching process (CBP) is a generalization of the classical Galton-Watson branching process, and, in the terminology of population dynamics, is used to describe the evolution of populations in which a control of the population size at each generation is needed. In this work, we deal with the problem of estimating the offspring parameters for a CBP assuming that the only observable data are the total number of individuals in each generation.We tackle the problem from a Bayesian perspective using MCMC and ABC methodologies. The results are illustrated with simulated data examples.
