Statistical inference for 2-type doubly symmetric critical irreducible continuous state and continuous time branching processes with immigration

Abstract

We study asymptotic behavior of conditional least squares estimators for 2-type doubly symmetric critical irreducible continuous state and continuous time branching processes with immigration based on discrete time (low frequency) observations.Comment: 67 pages. Estimation of a new parameter is added. In Section 2 we recall some notions and statements from arXiv:1403.0245 and arXiv:1404.224
