We propose a test statistic for detecting whether a differenced time series follows an invertible ARIMA process. The test follows a X2-1 distribution, it is easy to compute and shows an excellent performance when compared with standard optimal tests for overdifferencing.

Resumen (otros idiomas)

En este trabajo se propone un contraste estadístico para detectar invertibilidad en un proceso ARIMA. El estadístico tiene una distribución estandar X2-1 ,es fácil de calcular y presenta un excelente comportamiento al compararlo con los contrastes óptimos estandar de sobrediferenciación.
