Full Article Of Model Regresi Zero Inflated Poisson Pada Data Overdispersion

Overdispersion is a phenomenon of the data variance greater than the average One of the causes of overdispersion is too many zero value excess zero on the response variable 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
