Statistics seminar series University of New South Wales Session 1, 2006 Alan Welsh Centre for Mathematics and its Applications The Australian National University (based on work by Melissa Dobbie and A. H. Welsh) Modelling Correlated Zero-Inﬂated Count Data We will review the work carried out with Melissa Dobbie on constructing marginal models for count data with extra zeros which take into account correlation between repeated observations. The models are ﬁtted by generalized estimating equations (GEE) using available software and will be demonstrated on data from the Canberra Garden Bird Survey. Time permitting, we will discuss more recent work on random eﬀects models for count data with extra zeros. About the speaker: Alan Welsh is the E. J. Hannan Professor of Statistics at ANU. He is a proliﬁc and high impact researcher, having published over 70 papers in international statistics journals, and over 30 in top tier statistics journals. His research interests are primarily in statistical inference, statistical modelling, robust- ness and nonparametric methods. Time: 4pm, Wednesday, 3rd May Location: Room 4082, Red Centre Please join us after the seminar for wine and cheese in the staﬀroom. Seminar co-ordinator: David Warton e-mail: David.Warton@unsw.edu.au
