This paper considers the estimation problem for a trigonometric regression model with the noise specified by the Ornstein–Uhlenbeck
process with unknown parameter. We propose a sequential procedure which ensures a prescribed mean square precision uniformly
in the nuisance parameter. The asymptotic behaviour of the procedure duration mean has been studied.

In this paper a concentration inequality is proved for the deviation in the ergodic theorem for diffusion processes in the case of discrete time observations. The proof is based on geometric ergodicity of diffusion processes. We consider as an application the nonparametric pointwise estimation problem of the drift coefficient when the process is observed at discrete times. 相似文献

This paper is devoted to nonparametric estimation, through the
-risk, of a regression function based on observations with spherically symmetric errors, which are dependent random variables
(except in the normal case). We apply a model selection approach using improved estimates. In a nonasymptotic setting, an
upper bound for the risk is obtained (oracle inequality). Moreover asymptotic properties are given, such as upper and lower
bounds for the risk, which provide optimal rate of convergence for penalized estimators. 相似文献

We consider an insurance company in the case when the premium rate is a bounded non-negative random function ct and the capital of the insurance company is invested in a risky asset whose price follows a geometric Brownian motion with mean return a and volatility σ>0. If β?2a/σ2-1>0 we find exact the asymptotic upper and lower bounds for the ruin probability Ψ(u) as the initial endowment u tends to infinity, i.e. we show that C*u-β?Ψ(u)?C*u-β for sufficiently large u . Moreover if ct=c*eγt with γ?0 we find the exact asymptotics of the ruin probability, namely Ψ(u)∼u-β. If β?0, we show that Ψ(u)=1 for any u?0. 相似文献

This paper considers the statistical estimation problem of the root of a nonlinear function under observations of the nonlinear
regression model in continuous time. Asymptotic expansions for stochastic approximation averaging procedure are constructed,
the gain factor, which minimizes the asymptotic bias is found, asymptotic normality for the procedure is proved.
