Predictive information criterion for jump diffusion processes

Yuma Uehara

In this paper, we address a model selection problem for ergodic jump diffusion processes based on high-frequency samples. We evaluate the expected genuine log-likelihood function a…

Student t-Lévy regression model in YUIMA

Hiroki Masuda, Lorenzo Mercuri, Yuma Uehara

The aim of this paper is to discuss an estimation and a simulation method in the \textsf{R} package YUIMA for a linear regression model driven by a Student- Lévy process with co…

Quasi-Likelihood Analysis for Student-Lévy Regression

Hiroki Masuda, Lorenzo Mercuri, Yuma Uehara

We consider the quasi-likelihood analysis for a linear regression model driven by a Student-t Lévy process with constant scale and arbitrary degrees of freedom. The model is observ…

Noise Inference For Ergodic Lévy Driven SDE

Hiroki Masuda, Lorenzo Mercuri, Yuma Uehara

We study inference for the driving Lévy noise of an ergodic stochastic differential equation (SDE) model, when the process is observed at high-frequency and long time and when the…

Local Asymptotic Mixed Normality via Transition Density Approximation and an Application to Ergodic Jump-Diffusion Processes

Teppei Ogihara, Yuma Uehara

We study sufficient conditions for local asymptotic mixed normality. We weaken the sufficient conditions in Theorem 1 of Jeganathan (Sankhya Ser. A 1982) so that they can be applie…

Bootstrap method for misspecified ergodic Lévy driven stochastic differential equation models

Yuma Uehara

In this paper, we consider possibly misspecified stochastic differential equation models driven by Lévy processes. Regardless of whether the driving noise is Gaussian or not, Gauss…

Schwartz type model selection for ergodic stochastic differential equation models

Shoichi Eguchi, Yuma Uehara

We study the construction of the theoretical foundation of model comparison for ergodic stochastic differential equation (SDE) models and an extension of the applicable scope of th…

Estimating Diffusion With Compound Poisson Jumps Based On Self-normalized Residuals

Hiroki Masuda, Yuma Uehara

We consider parametric estimation of the continuous part of a class of ergodic diffusions with jumps based on high-frequency samples. Various papers previously proposed threshold b…

Statistical inference for misspecified ergodic Lévy driven stochastic differential equation models

Yuma Uehara

This paper deals with the estimation problem of misspecified ergodic Lévy driven stochastic differential equation models based on high-frequency samples. We utilize the widely appl…

Two-step estimation of ergodic Lévy driven SDE

Hiroki Masuda, Yuma Uehara

We consider high frequency samples from ergodic Lévy driven stochastic differential equation (SDE) with drift coefficient and scale coefficient involving unknown…
