el mas apropiado para representar la serie original y estimar valores futuros, encontrando que el modelo SARIMA presenta un mejor ajuste y predice de mejor manera el comportamiento de la misma. ABSTRACT This paper presents the results obtained by representing losses in a digital video transmission using ARIMA and SARIMA models. The experiments ( ( & !# $ & logy and using programming language R for the & ( models was conducted in order to determine what the most appropriate model was in order to represent the original series and estimate future values. The & ) * ching and better prediction of the original data set.
