Abstract
Forecasting consists basically of using data to predict the value of the attributes to promote micro- and macro-level decision making. There are many methods to do prediction extending from complexity and data requirement. In this paper, we present the method of an autoregressive integrated moving average (ARIMA), multilayer perceptron artificial neural network (ANN) model and decision tree (DT) method to forecast time-series data, also we use different methods to measure the accuracy of the forecasting of the patient dying after having Ebola virus in the Republic of Liberia over the period of 25 March 2014 to 13 April 2016. The data source is from World Health Organization (WHO).
