We are pleased to host our guest speaker Dr Alan Huang of The University of Queenland who will deliver his address via Zoom.


On arbitrarily underdispersed discrete distributions

Dr Alan Huang, School of Mathematics and Physics, The University of Queensland.

We review a range of popular generalized count distributions, investigating which (if any) can be arbitrarily underdispersed, i.e., its variance can be arbitrarily small compared to its mean. A philosophical implication is that models failing this criterion perhaps should not be considered a “statistical model” according to the extendibility criterion of McCullagh (2002). Four practical implications will be discussed. We suggest that all generalizations of the Poisson distribution be tested against this property.

About the Speaker

Dr Huang has an Honours degree in Science (Advanced Mathematics) from the University of Sydney, and a PhD (Statistics) from the University of Chicago on a McCormick Fellowship. He previously lectured at the University of Wisconsin-Madison and the University of Technology Sydney, before moving to the University of Queensland where he is currently the Statistics Major Convenor.
