Asymptotically optimal AR spectral estimate for multistep prediction
Karagrigoriou, Alex; Vonta, Filia (2000)This paper discusses the concept of asymptotic optimality from the frequency domain point of view making use of the direct method for multiple prediction. In particular, it is shown that with the use of a new autoregressive ...

A correlative study of quantitative EMG and biopsy findings in 31 patients with myopathies
Dardiotis, Efthymios; Papathanasiou, Eleftherios Stelios; Vonta, Filia; Hadjigeorgiou, Georgios M.; Zamba-Papanicolaou, Eleni; Kyriakides, Theodoros (2011)A direct correlation of QEMG with muscle biopsy findings might help delineate the sensitivity of QEMG in identifying muscle pathology as well as provide information on electrophysiological-histological correlations. In a ...

Entropy-Type Goodness-of-Fit Tests for Heavy-Tailed Distributions
Makrides, Andreas; Karagrigoriou, Alex; Vonta, Filia (Wiley Blackwell, 2013)The maximum entropy principle is a criterion for selecting a priori probabilities. Maximum entropy modeling has been successfully applied to computer vision, spatial physics, natural language processing and many other ...

Frailty models for arbitrarily censored and truncated data
Huber-Carol, C.; Vonta, Filia (2004)In this paper, we propose a frailty model for statistical inference in the case where we are faced with arbitrarily censored and truncated data. Our results extend those of Alioum and Commenges (1996), who developed a ...

Generalized divergence measures for survival and reliability data
Vonta, Filia; Karagrigoriou, Alex (2012)Measures of divergence or discrepancy are used either to measure mutual information concerning two variables or to construct model selection criteria. In this paper we are focusing on divergence measures that are based on ...

Intraperitoneal melatonin is not neuroprotective in the G93ASOD1 transgenic mouse model of familial ALS and may exacerbate neurodegeneration
Dardiotis, Efthymios; Panayiotou, Elena; Feldman, M. L.; Hadjisavvas, Andreas; Malas, Stavros; Vonta, Filia; Hadjigeorgiou, Georgios M.; Kyriakou, Kyriakos; Kyriakides, Theodoros (2013)In amyotrophic lateral sclerosis (ALS) reactive oxygen species and apoptosis are implicated in disease pathogenesis. Melatonin with its anti-oxidant and anti-apoptotic properties is expected to ameliorate disease phenotype. ...

A maximum entropy type test of fit
Lee, S.-J.; Vonta, Filia; Karagrigoriou, Alex (2011)In this paper, we propose a test of fit based on maximum entropy. The asymptotic distribution of the proposed test statistic is established and a corrected form for small and medium sample sizes is furnished. The performance ...

Maximum likelihood estimators: Nonparametric approach
Huber, C.; Solev, V. N.; Vonta, Filia (2007)In the paper, the maximum likelihood estimator for an unknown density is investigated. We deal with censored observations and construct a confidence region for this density. Bibliography: 4 titles. © 2007 Springer ...
