Title: Zero-inflated exponential families, with applications to count times-series Authors:  Alan Huang - University of Queensland (Australia) [presenting]

Abstract: A novel mechanism is introduced that generates exponential families of zero-inflated distributions from a given nominal distribution. This proves particularly useful for observation-driven times-series modelling of zero-inflated counts, where neither the underlying zero-inflation nor count processes are fully observable. The idea is demonstrated on two data analysis examples.
