Profile Summary

I am Professor of Econometrics at the School of Economics at the University of Nottingham. Broadly speaking, I work in the fields of econometric theory and statistics. Pretty much all my contributions contain a generous amount of asymptotic theory, sometimes using weak convergence, sometimes stronger modes (chiefly, almost sure convergence). Over the years, I have touched upon the following areas (listed in no particular order): - large factor models; - randomised tests; - the change point problem (testing and monitoring for structural change); - panel data; - cointegration and aggregation; - the random coefficient autoregressive model; - predicting mortality rates.
