The study focuses on simulated data generated using ARIMA(1, 1, 0) and applies both models for training and forecasting. Model performance is evaluated using MSE, AIC, and BIC. The models are further applied to neonatal mortality data from Saudi Arabia to assess their predictive capabilities. The results indicate that the NNAR model outperforms ARIMA in both training and forecasting. %K Time Series %K QRIMQ Model %K Neutral Network %K NNAR Model %U http://www.scirp.org/journal/PaperInformation.aspx?PaperID=140204
