Forecasting warranty claims considering dynamic over-dispersion [PDF]
International Journal of Production Economics, 2012 Forecasting warranty claims are vitally important for manufacturers in preparing their fiscal plans as well as in managing their inventory. One of the widely used forecasting models is the non-homogeneous Poisson process (NHPP), which assumes that the mean and the variance of the numbers of warranty claims at any given time interval are equal. However,

Towards the origins of over-dispersion in beta source calibration [PDF]
Radiation Measurements, 2018 Abstract The ability to deliver accurate and precise calibration doses is a central part of all trapped charge dating methods. Usually, the radiation source (α, β, X-ray) used to deliver these doses is, in turn, calibrated against an absolutely known reference source (usually a γ source) and many laboratories make use of Riso calibration quartz for ...

Statistical detection and modeling of the over-dispersion of winter storm occurrence [PDF]
Natural Hazards and Earth System Sciences, 2015 In this communication, I improve the detection and modeling of the over-dispersion of winter storm occurrence. For this purpose, the generalized Poisson distribution and the Bayesian information criterion are introduced; the latter is used for ...

Handling over-dispersion of performance indicators [PDF]
Quality and Safety in Health Care, 2005 A problem can arise when a performance indicator shows substantially more variability than would be expected by chance alone, since ignoring such "over-dispersion" could lead to a large number of institutions being inappropriately classified as "abnormal".

Evidence for Over-Dispersion in the Distribution of Clinical Malaria Episodes in Children [PDF]
PLoS ONE, 2008 It may be assumed that patterns of clinical malaria in children of similar age under the same level of exposure would follow a Poisson distribution with no over-dispersion. Longitudinal studies that have been conducted over many years suggest that some children may experience more episodes of clinical malaria than would be expected.

Testing the Odds of Inherent versus Observed Over-dispersion in Neural Spike Counts Odds of Inherent versus Observed Over-dispersion [PDF]
, 2016 The repeated presentation of an identical visual stimulus in the receptive field of a neuron may evoke different spiking patterns at each trial. Probabilistic methods are essential to understand the functional role of this variance within the neural activity. In that case, a Poisson process is the most common model of trial-to-trial variability.

Investigating over-dispersion; Moniliformis (Acanthocephala) and rats
Parasitology, 1984 SUMMARYAn analysis of the frequency distribution of numbers of Moniliformis dubius in rats of an outbred strain of Wistar origin (CFHB) and feeding ad libitum on Oxoid 41B diet, showed that over-dispersion occurred regardless of the age and sex of the rats and the infective dose given (12, 20 or 40 cystacanths/rat). Over-dispersion was also shown to be

On the nature of over-dispersion in motor vehicle crash prediction models
Accident Analysis & Prevention, 2007 Statistical modeling of traffic crashes has been of interest to researchers for decades. Over the most recent decade many crash models have accounted for extra-variation in crash counts--variation over and above that accounted for by the Poisson density.
