Handling excess zeros in count models for recreation demand analysis without apology

Martinez-Cruz, Adan - 2016

Hurdle and zero-in ated models are the two foremost methods used to deal with excess zeros. However, their reliance on … represent a theoretically consistent alternative to handle excess zeros. The theoretical model behind a latent class model does … not require the non-participation assumption. Instead, excess zeros is explained as the accumulation of corner solutions …

A dynamic hurdle model for zero-inflated count data: With an application to health care utilization

Baetschmann, Gregori; Winkelmann, Rainer - 2014

A Dynamic Hurdle Model for Zero-Inflated Count Data: With an Application to Health Care UtilizationExcess zeros are encountered in many empirical count data applications. We provide a new explanation of extra zeros, related to the underlying stochastic process that generates events. The process...

Capturing the zero: A new class of zero-augmented distributions and multiplicative error processes

Hautsch, Nikolaus; Malec, Peter; Schienle, Melanie - 2011

We propose a novel approach to model serially dependent positive-valued variables which realize a non-trivial proportion of zero outcomes. This is a typical phenomenon in financial time series observed at high frequencies, such as cumulated trading volumes. We introduce a flexible point-mass...

Estimation issues in disaggregate gravity trade models

Prehn, Sören; Brümmer, Bernhard - 2011

French (2011) can analytically show that the standard Anderson and van Wincoop (2003) gravity trade model is only correctly specified for disaggregate data; gravity trade model analysis should be done at product level and then estimation results should be reaggregated. If however gravity trade...
