Zero-Inflated Poisson Regression, with an Application to.
In this paper, the semi varying coefficient zero-inflated generalized Poisson model is discussed based on penalized log-likelihood. All the coefficient functions are fitted by penalized spline (P-spline), and Expectation-maximization algorithm is used to drive these estimators. The estimation approach is rapid and computationally stable.
Recently, the zero-inflated generalized Poisson regression model is defined as a good alternate to model count data with too many zeros (the authors, Zero inflated generalized Poisson regression.
Zero-inflated models have found applications in situa-tions where excess number of zero observations are gen-erated. The application of the zero-inflated Poisson model by Lambert (1) in a count regression model is well known. Recently Couturier et al. (2) have used the zero- inflated truncated generalized Pareto distribution for the.
In probability theory, the zero-truncated Poisson (ZTP) distribution is a certain discrete probability distribution whose support is the set of positive integers. This distribution is also known as the conditional Poisson distribution or the positive Poisson distribution. It is the conditional probability distribution of a Poisson-distributed random variable, given that the value of the random.

Zero inflated Poisson regression model (ZIP) is one of the method that can be used to overcome problems due to excess zeros. The purpose of this research is to estimate the regression parameters model Zero -inflated Poisson (ZIP) and applying to the data of unsuccessful students in national examinations in senior high school and vocational school in the city of Mataram.
