Descrição:
- Resumo: When it comes to estimating volatility in financial returns the literature on stochastic volatility models is enormous. These models are flexible enough to capture the nonlinear behaviour usually observed in financial time series of returns.However, SV models rely on pre-modelling the original series to avoid the simultaneous estimation of the mean and variance. To tackle this problem an SV in mean (SVM) model was proposed in which the unobserved volatility is incorporated as an explanatory variable in the mean equation of the returns. In this work we investigate recent advances in the Bayesian analysis of these models.
