      Nonlinear Poisson autoregression 

      Fokianos, Konstantinos; Tjøstheim, D. (2012)
      We study statistical properties of a class of non-linear models for regression analysis of count time series. Under mild conditions, it is shown that a perturbed version of the model is geometrically ergodic and possesses ...
