TITLE: 'Spatio-temporal point processes: two problems, two approaches'
SPEAKER: Professor Peter Diggle (Department of Mathematics and Statistics, Lancaster University)

VENUE: Scottish Agricultural College, Sratherrick Rd, Inverness
ABSTRACT:
Spatio-temporal point process data arise naturally in a number of
disciplines, including (human or veterinary) epidemiology where
extensive data-sets are also becoming more common. In this talk I
will describe two approaches to the analysis of spatio-temporal point
process data, each motivated by a particular application as follows:
1) empiral modelling, exemplified by a log-Gaussian Cox process model
for real-time monitoring of gastro-enteric disease in southern
England;
2) mechanistic modelling, exemplified by a model due to Matt Keeling
(Warwick University) for the 2001 UK foot-and-mouth epidemic.
I will compare different approaches to inference, including maximum
likelihood and a computationally simple partial likelihood
alternative.
