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…

Robustified Gaussian quasi-likelihood inference for volatility

Shoichi Eguchi, Hiroki Masuda

We consider statistical inference for a class of continuous semimartingale regression models based on high-frequency observations subject to contamination by finite-activity jumps…
