On sequential estimation for branching processes with immigration.
A Galton-Watson process with immigration is considered. A class of two-stage estimators for the offspring mean is constructed and its limit properties are studied. The stopping rule of \textit{T.\ N.\ Sriram} et al. [Ann. Stat. 19, No. 4, 2232--2243 (1991)] is used. A small simulation study is conducted.
