Asymptotic behavior of a multi-type nearly critical Galton--Watson processes with immigration
László Györfi, Márton Ispány, Péter Kevei +1
Multi-type inhomogeneous Galton--Watson process with immigration is investigated, where the offspring mean matrix slowly converges to a critical mean matrix. Under general conditio…
Asymptotic behavior of CLS estimators for -type doubly symmetric critical Galton-Watson processes with immigration
Márton Ispány, Kristóf Körmendi, Gyula Pap
In this paper, the asymptotic behavior of the conditional least squares (CLS) estimators of the offspring means and of the criticality parameter for a -ty…
Asymptotic behavior of critical primitive multi-type branching processes with immigration
Márton Ispány, Gyula Pap
Under natural assumptions a Feller type diffusion approximation is derived for critical multi-type branching processes with immigration when the offspring mean matrix is primitive…
Poisson limit of an inhomogeneous nearly critical INAR(1) model
László Györfi, Márton Ispány, Gyula Pap +1
An inhomogeneous first--order integer--valued autoregressive (INAR(1)) process is investigated, where the autoregressive type coefficient slowly converges to one. It is shown that…
