Head of Applied Research

As Model Research Scientist Alvin spearheads SAPIAT’s theoretical modelling efforts of financial markets. Alvin has worked extensively with linear factor models of security returns since the early 1980’s in the areas of value-at-risk and security performance. His thesis, “Heteroskedasticity and the Estimation of Systematic Risk”, demonstrates that the the contemporaneous estimation bias (CEB) in testing of linear factor models of security returns is due to the misapplication OLS estimation in certain patterns of heterogeneous errors.
He has worked extensively with the EM algorithm for factor analysis in developing extensions to a variety of financial models. Alvin holds a PhD in Finance from Graduate School of Business at University of Wisconsin-Madison.
