Aspect in the L2 and L3 Acquisition of Greek
Karpava, Sviatlana; Grohmann, Kleanthes K.; Fokianos, Konstantinos (Springer, 2012)

Article
Aspect in the L2 and L3 acquisition of Greek
Karpava, S.; Grohmann, K. K.; Fokianos, Konstantinos (2012)This paper investigates different facets of the second language acquisition of Modern Greek by native speakers of Russian and Georgian, both adults and children, in the domain of aspectual marking in embedded clauses. The ...

Asymptotic properties of quasimaximum likelihood estimators in observationdriven time series models∗
Douc, R.; Fokianos, Konstantinos; Moulines, E. (2017)We study a general class of quasimaximum likelihood estimators for observationdriven time series models. Our main focus is on models related to the exponential family of distributions like Poisson based models for count ...

Article
Biological applications of time series frequency domain clustering
Fokianos, Konstantinos; Promponas, Vasilis J. (2012)Clustering methods are used routinely to form groups of objects with similar characteristics. Collections of time series datasets appear in several biological applications. Some of these applications require grouping the ...

Article
Clustering of biological time series by cepstral coefficients based distances
Savvides, A.; Promponas, Vasilis J.; Fokianos, Konstantinos (2008)Clustering of stationary time series has become an important tool in many scientific applications, like medicine, finance, etc. Time series clustering methods are based on the calculation of suitable similarity measures ...

Comments on: Some recent theory for autoregressive count time series
Fokianos, Konstantinos (2012)

Article
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–Ljungtype test statistic that is formed after calculating the distance covariance function among ...

Corrigendum to "On weak dependence conditions: The case of discrete valued processes" [Statist. Probab. Lett. 82 (2012) 19411948]
Doukhan, P.; Fokianos, Konstantinos; Li, X. (2013)

Article
Count Time Series Models
Fokianos, Konstantinos (2012)We review regression models for count time series. We discuss the approach that is based on generalized linear models and the class of integer autoregressive processes. The generalized linear models' framework provides ...

Article
DCovTS: Distance covariance/correlation for time series
Pitsillou, M.; Fokianos, Konstantinos (2016)The distance covariance function is a new measure of dependence between random vectors. We drop the assumption of iid data to introduce distance covariance for time series. The R package dCovTS provides functions that ...

Article
Density ratio model selection
Fokianos, Konstantinos (2007)The density ratio model presumes that the loglikelihood ratio of two unknown densities is of some known parametric linear form. However, the choice of the functional form has an impact on both estimation and testing. The ...

Theodotou, Marios; Fokianos, Konstantinos; Mouzouridou, Alexia; Konstantinou, Cornelia; Aristotelous, Andrea; Prodromou, Dafni; Chrysikou, Asimina (2017)The aim of this clinical trial was to investigate the effects of Evelor, a micronized formulation of resveratrol (RESV

Article
Effect of resveratrol on nonalcoholic fatty liver disease
Theodotou, Marios; Fokianos, Konstantinos; Moniatis, Demetris; Kadlenic, Rudolf; Chrysikou, Asimina; Aristotelous, Andrea; Mouzouridou, Alexia; Diakides, John; Stavrou, Eliza (2019)The aim of the present study was to investigate the effect of a micronized formulation of transresveratrol in humans with nonalcoholic fatty liver disease (NAFLD). TransResveratrol has been used in the form of micronized ...

Estimation and testing linearity for nonlinear mixed poisson autoregressions
Christou, V.; Fokianos, Konstantinos (2015)Nonlinear mixed Poisson autoregressive models are studied for the analysis of count time series. Given a correct mean specification of the model, we discuss quasi maximum likelihood estimation based on Poisson loglikelihood ...

Article
A generalizedmoments specification test for the logistic link
Fokianos, Konstantinos; Peng, A.; Qin, J. (1999)The authors consider the problem of testing the validity of the logistic regression model using a random sample. Given the values of the response variable, they observe that the sample actually consists of two independent ...
