Perbandingan Model Generalized Poisson Regression dan Regresi Binomial Negatif pada Jumlah Kasus Pneumonia Balita di Provinsi Jawa Timur
Keywords:
pneumonia, Generalized Poisson Regression (GPR), negative binomial regressionAbstract
Pneumonia in children under five is one of the leading causes of death among children worldwide. In Indonesia, East Java Province ranks seventh in terms of the number of cases of pneumonia in children under five. In 2024, there were 99,048 cases of pneumonia in children under five in the province. The number of cases of pneumonia in children under five is discrete data that often experiences overdispersion, making Poisson regression unsuitable for use. This study aims to compare the Generalized Poisson Regression (GPR) model and negative binomial regression and identify factors that influence cases of pneumonia in children under five in East Java Province. This study uses secondary data on the number of cases of pneumonia in children under five at the district/city level in East Java Province in 2024. Based on the results of the study, it was found that the negative binomial regression model was the best model with an Akaike Information Criterion (AIC) value of 652.37. The factors that had a positive effect were the percentage of infants receiving vitamin A, while the factors that had a negative effect were the percentage of low birth weight infants.
