      The effects of applying cell-suppression and perturbation to aggregated genetic data 

      Antoniades, Athos; Keane, J.; Aristodimou, Aristos; Philipou, Christa; Constantinou, Andreas I.; Georgousopoulos, Christos; Tozzi, Federica; Kyriacou, Kyriacos C.; Hadjisavvas, Andreas; Loizidou, Maria A.; Demetriou, Christiana A.; Pattichis, Constantinos S. (2012)
      The key test for confidence in any association discovered within the medical domain is replication testing. That is, the ability of the association to be detected in independent populations. At the same time, in order to ...

      Log-linear Poisson autoregression 

      Fokianos, Konstantinos; Tjøstheim, D. (2011)
      We consider a log-linear model for time series of counts. This type of model provides a framework where both negative and positive association can be taken into account. In addition time dependent covariates are accommodated ...

      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 ...

      Some recent progress in count time series 

      Fokianos, Konstantinos (2011)
      We reviewsome regression models for the analysis of count time series. These models have been the focus of several investigations over the last years, but only recently simple conditions for stationarity and ergodicity ...
