Centre at Queen's University Belfast. The speaker will be Malcolm Faddy
from the Queensland University of Technology. Details of the talk are as
follows:
Dispersion Modelling for Count Data
Abstract: The standard discrete distributions binomial, Poisson and
negative binomial have an equivalent representation in terms of Markov
(birth) processes. By generalising the transition rates of such
processes, more general distributions exhibiting both over- and
under-dispersion can be constructed. Covariates can also be incorporated
into the transition rates, leading to a very general modelling
framework. The resulting methodology will be illustrated using a number
of data sets old and new.
ALL VERY WELCOME
