On a Universal Strictly Decreasing Nonparametric Estimator Applied to the Drift Function of a Recurrent Diffusion Process Estimation

Nicolas Marie

The paper proposes a continuously differentiable, strictly decreasing nonparametric estimator for the drift function of recurrent diffusion processes, providing non‑asymptotic L¹ r…

Fixed-Point Estimation of the Drift Parameter in Stochastic Differential Equations Driven by Rough Multiplicative Fractional Noise

Chiara Amorino, Laure Coutin, Nicolas Marie

We investigate the problem of estimating the drift parameter from independent copies of the solution of a stochastic differential equation driven by a multiplicative fractional…

Nadaraya-Watson Type Estimator of the Transition Density Function for Diffusion Processes

Nicolas Marie, Ousmane Sacko

This paper deals with a nonparametric Nadaraya-Watson (NW) estimator of the transition density function computed from independent continuous observations of a diffusion process. A…

Nonparametric Estimation from Correlated Copies of a Drifted Process

Nicolas Marie

This paper presents several situations leading to the observation of multiple correlated copies of a drifted process, and then non-asymptotic risk bounds are established on nonpara…
