Robustified Gaussian quasi-BIC for volatility

Shoichi Eguchi, Hiroki Masuda

We develop a theoretical foundation for robust model comparison in a class of non-ergodic continuous volatility regression models contaminated by finite-activity jumps. Using the d…

LAD estimation of locally stable SDE

Oleksii M. Kulyk, Hiroki Masuda

We prove the asymptotic mixed normality of the least absolute deviation (LAD) estimator for a locally I^±-stable stochastic differential equation (SDE) observed at high frequency,…

Statistical inference for ergodic diffusion with Markovian switching

Yuzhong Cheng, Hiroki Masuda

This study explores a Gaussian quasi-likelihood approach for estimating parameters of diffusion processes with Markovian regime switching. Assuming the ergodicity under high-freque…

Quasi-likelihood-based EM algorithm for regime-switching SDE

Yuzhong Cheng, Hiroki Masuda

This paper considers estimating the parameters in a regime-switching stochastic differential equation(SDE) driven by Normal Inverse Gaussian(NIG) noise. The model under considerati…
