The public lecture
Professor: Ostap Okhrin
Dresden University of Technology
This talk is based on three works, that are dealing with the changing dependence over time: adaptive estimation, hidden Markov models and realized copula models. In the first case we estimate the copula parameter (and structure) together with the interval on which the model is homogeneous. In the second case we assume several states of the copula as the underlying distribution and estimate them as well as the transition probabilities. In the last model we estimate the copula based on the high-frequency data. This is one of the first approaches that allows for copula in high-frequency financial econometrics.
