“…Recent developments include nonparametric method in Bianchi (2007), Markov chain Monte Carlo method in Kalogeropoulos (2007) and Golightly and Wilkinson (2008), and Hermite polynomials approximation in Aït-Sahalia (2008). The method in Aït-Sahalia (2008) offers a closed-form expansion for the transition density and yields high numerical precision for a large class of SDEs.…”
This paper introduces quasi-maximum likelihood estimator for multivariate di¤usions based on discrete observations. A numerical solution to the stochastic di¤erential equation is obtained by higher order Wagner-Platen approximation and it is used to derive the …rst two conditional moments. Monte Carlo simulation shows that the proposed method has good …nite sample property for both normal and non-normal di ¤usions. In an application to estimate stochastic volatility models, we …nd evidence of closeness between the CEV model and the GARCH stochastic volatility model. This …nding supports the discrete time GARCH modeling of market volatility.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
