چکیده

We derive a nonlinear filter and the corresponding filter-based estimates for a threshold autoregressive stochastic volatility, (TARSV), model. Using the technique of a reference probability measure, we derive a nonlinear filter for the hidden volatility and related quantities. The filter-based estimates for the unknown parameters are then obtained from the EM algorithm.

Online Particle Filtering of Stochastic Volatility

A method for online estimation of the volatility when observing a stock price is proposed. This is based on modeling the volatility dynamics as a stochastic differential equation that is constructed using a technique from the control theory [1]. Identification of the model parameters using the observations is proposed afterwards [2]. It is based on some stochastic calculus. Volatility estimatio...

A Threshold Stochastic Volatility Model with Realized Volatility

Rapid development in the computer technology has made the financial transaction data visible at an ultimate limit level. The realized volatility, as a proxy for the ”true” volatility, can be constructed using the high frequency data. This paper extends a threshold stochastic volatility specification proposed in So, Li and Lam (2002) by incorporating the high frequency volatility measures. Due t...

Modelling Bilinear Stochastic Volatility

Some relationships between ARCH-type and Stochastic Volatility models are investigated. New model formulations are derived through a transformation of a GARCH-M process and the name Generalized Bilinear Stochastic Volatility is suggested. Markovian-type representations are presented and estimation algorithms are proposed.

NCER Working Paper Series Estimating Stochastic Volatility Models Using a Discrete Non-linear Filter

Many approaches have been proposed for estimating stochastic volatility (SV) models, a number of which are filtering methods. While non-linear filtering methods are superior to linear approaches, non-linear filtering methods have not gained a wide acceptance in the econometrics literature due to their computational cost. This paper proposes a discretised non-linear filtering (DNF) algorithm for...
