Multivariate stochastic variance models
Andrew Harvey,Esther Ruiz,Neil Shephard +2 more
- 01 Jan 1994
TL;DR: In this article, a multivariate model based on autoregressive conditional heteroscedasticity (ARCH) is proposed to capture common movements in volatility in a very natural way.

Quasi-maximum likelihood estimation of stochastic volatility models
TL;DR: In this article, the asymptotic and finite sample properties of a quasi-maximum likelihood estimator based on the Kalman filter were analyzed for daily observations on the yen/dollar exchange rate.

Persistence and Kurtosis in GARCH and Stochastic Volatility Models
TL;DR: This paper showed that the relationship between kurtosis, persistence of shocks to volatility, and first-order autocorrelation of squares is different in GARCH and ARSV models.
Bootstrap prediction for returns and volatilities in GARCH models
TL;DR: A new bootstrap procedure to obtain prediction densities of returns and volatilities of GARCH processes is proposed, which allows incorporation of parameter uncertainty and does not rely on distributional assumptions.

Frontiers in VaR forecasting and backtesting
María Rosa Nieto,Esther Ruiz +1 more
TL;DR: There are vast numbers of alternative methods for constructing and evaluating value at risk (VaR) forecasts as mentioned in this paper, which are used as a testing ground when fitting alternative models for representing the dynamic evolution of time series of financial returns.
