WebDickey-Fuller test (ADF). his test is a part of the methodology implemented by Dickey and Fuller (1979, p. 430) as a way of testing stationarity in time series. According to Campbell and Lo (1997), unit root test is constructed in a way that the null hypothesis expects time series to be stationary at irst diference, while the alternative hypothesis WebDickey, D.A. and Fuller, W.A.

WebDickey (1976) and Dickey and Fuller (1979) studied the limiting distribution of the OLS estimator of autoregressive models for time series with a simple unit root. Dickey, Hasza, and Fuller (1984) obtained the limiting distribution for time series with seasonal unit roots. Hamilton (1994) discusses the various types of unit root testing. ... WebEn el caso de los contrastes de raíces unitarias tipo ADF basados en las propuestas de Dickey y Fuller (1979), la presencia de cambios en series estacionarias hace que el estimador del parámetro autorregresivo se aproxime a la unidad, conduciendo al no rechazo de la hipótesis de raíz unitaria. Una vez puesta de manifiesto esta limitación ... how many solutions graph
