A general test for time dependence in parameters (replication data)
A new test for time-dependent parameters is proposed. The Trig-test is based on a trigonometric expansion to approximate the unknown functional form of the variation in the... -
A non-linear filtering approach to stochastic volatility models with an appli...
This paper develops a new model for the analysis of stochastic volatility (SV) models. Since volatility is a latent variable in SV models, it is difficult to evaluate the exact...
