Zero-inflated negative binomial model is an appropriate choice to count response variables with excessive zeros and over-dispersion simultaneously. This paper addressed parameter estimation in the zero-inflated when there are many parameters, so that some of them have not influence on variable. We proposed based linear shrinkage, pretest, shrinkage pretest, Stein-type, and positive Stei...
(a) Obtain the expression for the deviance for comparison of the full model, which assumes a different µ i for each y i , with a reduced model defined by a Poisson GLM with link function g(·).
Poisson regression and negative binomial regression have been widely used to model the road crashes and to predict crash frequency. Zero inflated models have been shown to be a powerful tool to predict crash frequency when crash data are characterized by preponderance of zero. This paper presents the research work aiming to correlate the road traffic crash rate with road geometry and traffic ch...
Analysis of count data is required in many areas of biometric interest. Often the simple Poisson distribution is not appropriate, since an extra-number of zero counts occur in the count data. Some current approaches for the problem at hand are reviewed. It will be argued that these situations can often be easily modeled using the zero-inflated Poisson distribution. A variety of applications are...
