I retired 2010 as a research statistician in the Applied Maths Group at Industrial Research Ltd, Lower Hutt, New Zealand.
Research interests include climate change, extreme value theory, accurate inference, cusum theory, bias reduction, finite samples, and adjusting for rounding.
I've also modelled cellphones and reverberations systems for clients within IRL.
And a number of other things.


I've developed estimation theory for mixtures of distributions and applied it to rainfall.
I've modelled temperature and riverflow series, and applied cusum extensions to detect trend and changing variability in climate series.
I've modelled the effect of trend and changing variability on extremes (eg extreme temperature).
Recently I've been developing theory to study the extremes of correlated time series.
