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 quasi-maximum likelihood estimators in observation-driven time series models∗

Douc, R.; Fokianos, Konstantinos; Moulines, E. (2017)

We study a general class of quasi-maximum likelihood estimators for observation-driven time series models. Our main focus is on models related to the exponential family of distributions like Poisson based models for count ...

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 ...

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 ...

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 ...

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 ...

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 ...

Density ratio model selection

Fokianos, Konstantinos (2007)

The density ratio model presumes that the log-likelihood 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 ...

Estimation and testing linearity for non-linear mixed poisson autoregressions

Christou, V.; Fokianos, Konstantinos (2015)

Non-linear 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 log-likelihood ...

A generalized-moments 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 ...
