Cramér moderate deviations for a supercritical Galton-Watson process

Abstract
Let be a supercritical Galton-Watson process. The Lotka-Nagaev estimator is a common estimator for the offspring mean.In this paper, we establish some Cram\'{e}r moderate deviation results for the Lotka-Nagaev estimator via a martingale method. Applications to construction of confidence intervals are also given.
