Statistical inference for discrete-time samples from affine stochastic delay differential equations
asymptotic normality composite likelihood consistency discrete time observation of continuous-time models prediction-based estimating functions pseudo-likelihood stochastic delay differential equation
2013/4/28
Statistical inference for discrete time observations of an affine stochastic delay differential equation is considered. The main focus is on maximum pseudo-likelihood estimators, which are easy to cal...
Causal band-limited approximation and forecasting for discrete time processes
band-limited processes discrete time processes causal filters sampling low-pass filters forecasting.
2012/9/18
We study causal dynamic approximation of non-bandlimited discretetime processes by band-limited discrete time processes such that a part of the historical path of the underlying process is approximate...

Let (X(t); f E N') be a random sequence adopted to .
a filtration (Ft)in (a,F ,P ) satisfying some natural assumption. If
none of the events (X (t + 1) > X (t)), (X (t + 1) < X (t)) can be predicted...
Discrete time portfolio selection with proportional transaction cost
PortfoIio selection Transaction costs Bellman equation
2009/9/22
In the paper discrete time portblio selection with
maximization of a discounted satisfaction functional is studied. In Section
2 the case without transaction costs is considered and explint

Discrete time periodically correlated Markov processes
periodically correlated proasses Markov processes covariance characterization
2009/9/22
We consider a discrete time periodically correlated
process {X.} which is also Markov in the wide sense. We provide
closed formulas for the covariance function R (n, m) = EX, X, and for
the spectra...

Princing European options on instruments with a constant dividend yield:The randomized discrete-time approach
Option pricing dividends randomization alternative models
2009/9/21
Due to the well-known fact that market returns are not
normally distributed, we use generalized hyperbolic distributions for
pricing options in a randomized discrete-time setup. The obtained
formul...

We consider a ψ-irreducible, discrete-time Markov chain on a general state space with transition kernel P. Under suitable conditions on the chain, kernels can be treated as bounded linear operators...

2009/3/23
Given a set-valued stochastic process (Vt)t=0,...,T, we say that the martingale selection problem is solvable if there exists an adapted sequence of selectors ξt in Vt, admitting an equivalent marting...

Discrete time nonlinear filters informative observation
2009/3/23
The nonlinear filter associated with the discrete time signal-observation model $(X_k,Y_k)$ is known to forget its initial condition as $ktoinfty$ regardless of the observation structure when the sign...
Estimation of the spectral density of a homogeneous random stable discrete time field
homogeneous stable fields spectral density estimate
2009/2/23
In earlier papers, 2π-periodic spectral data windows have been used in spectral estimation of discretetime random fields having finite second-order moments. In this paper, we show that 2π-periodic spe...
