Zero inflated Poisson and negative binomial regression models: application in education
Background: The number of failed courses and semesters in students are indicatorsof their performance. These amounts have zero inflated (ZI) distributions. Using ZI Poisson and negative binomial distributions we can model these count data to find the associated factors and estimate the parameters. This study aims at to investigate the important factors related to the educational performance of ...

متن کاملNew Multivariate Zero-inflated Binomial Distribution with Application
A new multivariate zero-inflated binomial distribution has the purpose of analyzing the multivariate proportional data with excessive zeros. The distributional properties of the purposed model are discussed. The Newton Raphson, Fisher score and expectation maximization algorithm are developed for estimating parameters of interest. The score test and the likelihood ratio test are derived for ass...
