Gary Keogh - Research Statement
Theoretical Statistics
I have two primary interests here
1.
Many physical systems which are chaotic in nature can be modelled
succesfully using statistical methods,
yet
chaotic systems are in fact deterministic. On the other hand when
random variables are to be simulated
on
computer this is achieved by creating chaotic sequences of
numbers, which of course are anything but
random. Im interested in the relationships between these
two types of modelling uncertainity.
2.
Im also interested in the problems of detecting and
remedying mis-specifications in multiple regression
models. In particular, testing for autocorrelation and
multicollinearity in such models.
Applied Statistics
Under this heading I have a range of
interests (which I hope is always expanding). It is my belief
that work in
Applied Statistics is not only useful in itself but is often the
source of inspiration for new theoretical ideas.
Recently Ive worked in
1. Educational Science (the efficacy of computer delivery of course material)
2. Information Retrieval (search engine evaluation)
3. Econophysics (analysis of stock market volatility)
4.
Scientometrics (evolution of a conference over 25 years)
