This process depends on the efficiency $\{p_n\}_n$ of replication of the molecules, $p_n$ being the probability that a molecule will duplicate at replication cycle $n$. Assuming $p_n=p$ for all $n$, we propose to estimate the unknown parameter $\theta=(p, X_0)$ in a Bayesian framework under a Bienaym\'e-Galton-Watson branching model of the amplification process. The Bayesian approach allows us to take into account some prior information on the parameter. We build and study Bayesian estimators and sets of credibility of the parameter by Markov Chain Monte Carlo methods.
