Joint Structural Break Detection and Parameter Estimation in High-Dimensional Non-Stationary VAR Models

 

Assuming stationarity is unrealistic in many time series applications. A more realistic alternative is to

allow for piecewise stationarity, where the model is allowed to change at given time points. In this talk, we propose a

three-stage procedure for consistent estimation of both structural change points and parameters of high- Read more about Dept. Seminar - Abolfazl Safikhani

Semi-parametric method for non-ignorable missing in longitudinal data using refreshment samples.

Missing data is one of the major methodological problems in longitudinal studies. It not only reduces the sample size, but also can result in biased estimation and inference. It is crucial to correctly understand the missing mechanism and appropriately incorporate it into the estimation and inference procedures.  Read more about Dept. Seminar - Lan Xue

Models on Testing Predictability of Asset Returns

 

Testing predictability of asset returns is a cornerstone issue in modern asset pricing

and the related fields. It has been one of the hottest research topics in asset pricing

field in the recent two decades. In this talk, I will combine several of my own papers

(published papers and ongoing projects) on testing predictability of asset returns and Read more about Dept. Seminar - Zongwu Cai
