Generalized multiple change-point detection in the structure of multivariate, possibly high-dimensional, data sequences
Andreas Anastasiou, Angelos Papanastasiou
The extensive emergence of big data techniques has led to an increasing interest in the development of change-point detection algorithms that can perform well in a multivariate, po…
Modeling of Covid-19 Pandemic in Cyprus
Sergios Agapiou, Andreas Anastasiou, Anastassia Baxevani +6
The Republic of Cyprus is a small island in the southeast of Europe and member of the European Union. The first wave of COVID-19 in Cyprus started in early March, 2020 (imported ca…
Normal Approximation for Stochastic Gradient Descent via Non-Asymptotic Rates of Martingale CLT
Andreas Anastasiou, Krishnakumar Balasubramanian, Murat A. Erdogdu
We provide non-asymptotic convergence rates of the Polyak-Ruppert averaged stochastic gradient descent (SGD) to a normal random vector for a class of twice-differentiable test func…
Bounds for the asymptotic distribution of the likelihood ratio
Andreas Anastasiou, Gesine Reinert
In this paper we give an explicit bound on the distance to chisquare for the likelihood ratio statistic when the data are realisations of independent and identically distributed ra…
