      Asymptotic results for non I.I.D. multidimensionally indexed random variables 

      Mavrikiou, Petroula M. (Πανεπιστήμιο Κύπρου, Σχολή Θετικών και Εφαρμοσμένων Επιστημών / University of Cyprus, Faculty of Pure and Applied Sciences, 1999-06)
      Ο τομέας των τυχαίων μεταβλητών με πολυδιάστατους δείκτες είναι ένας πολύ γρήγορα αναπτυσσόμενος τομέας στις Πιθανότητες και στη Στατιστική. Η διατριβή αυτή πραγματεύεται ασυμπτωτικά αποτελέσματα για τις πιο πάνω τυχαίες ...

      Consistent Testing for Pairwise Dependence in Time Series 

      Fokianos, Konstantinos; Pitsillou, M. (2017)
      We consider the problem of testing pairwise dependence for stationary time series. For this, we suggest the use of a Box–Ljung-type test statistic that is formed after calculating the distance covariance function among ...

      Marginal analysis on binary pairwise Gibbs random fields 

      Le, T.; Hadjicostis, Christoforos N. (2011)
      In this paper, we study marginal problems for a class of binary pairwise Gibbs random fields (BPW-GRFs). Given a BPW-GRF associated with a family of binary positive pairwise potentials, finding the exact marginal for each ...

      Nonlinear estimation for a class of systems 

      Socratous, Y.; Rezaei, F.; Charalambous, Charalambos D. (2009)
      This paper considers nonlinear estimation problems for classes of models, and employs relative entropy to describe the uncertainty classes. Two optimization problems are formulated on general Banach spaces, and their ...

      Poisson approximation for a sum of dependent indicators: An alternative approach 

      Papadatos, Nickos; Papathanasiou, Vassilis (2002)
      The random variables X1, X2,...,Xn are said to be totally negatively dependent (TND) if and only if the random variables Xi and Σj≠i Xj are negatively quadrant dependent for all i. Our main result provides, for TND 0-1 ...

      Primal and dual problems in electrical impedance imaging 

      Polydorides, N.; Charalambous, Charalambos D. (2005)
      Ill-posed inverse boundary value problems are usually approached as problems of inference under a given set of boundary observations. The parameters and data are modelled as random variables so that to encompass the ...

      Probability and moment inequalities for demimartingales and associated random variables 

      Hadjikyriakou, Milto (Πανεπιστήμιο Κύπρου, Σχολή Θετικών και Εφαρμοσμένων Επιστημών / University of Cyprus, Faculty of Pure and Applied Sciences, 2010-11)
      Τα τελευταία χρόνια έχουν μελετηθεί εκτενώς οι διάφορες έννοιες εξάρτησης τυχαίων μεταβλητών. Ιδιαίτερο ενδιαφέρον παρουσιάζουν οι έννοιες της θετικής και αρνητικής συσχέτισης. Στη βιβλιογραφία γίνονται αναφορές και σε ...

      Stochastic power control for time-varying flat fading wireless channels 

      Olama, M. M.; Shajaat, S. M.; Djouadi, S. M.; Charalambous, Charalambos D. (2005)
      The performance of stochastic optimal power control of time-varying wireless short-term flat fading channels, in which the evolution of the dynamical channel is described by a stochastic state space representation, is ...
