摘要:

In this talk, the speaker will present a new volatility model by allowing spatially varying coefficients in spatial generalized autoregressive conditional heteroskedasticity (SGARCH) models. This model captures volatility behaviors over space and investigates the relationship between some explanatory variables and the volatility at each location. A two-stage quasi-likelihood maximization via BPST is developed to estimate the model over a complicated domain. The speaker will also present the theoretical properties of the proposed estimators. We conduct both simulation studies and real-data applications to demonstrate the performance of our approach.
