The KPSS test is often used to complement Dickey-Fuller-type tests. I will touch on how to interpret such combined results in a future post.

Webband Perron (Econometrica, 2000). They have established that use of this MAIC criterion may provide “huge size improvements” (2000, abstract) in the dfgls test. The criterion, indicating the appropriate lag order, is printed on dfgls’ output, and may be used to select the test statistic from which inference is to be drawn.

WebbTo estimate sigma^2 the Newey-West estimator is used. If lshort is TRUE, then the truncation lag parameter is set to trunc (4* (n/100)^0.25), otherwise trunc (12* (n/100)^0.25) is used. The p-values are interpolated from Table 4.2, page 103 of Banerjee et al (1993). Missing values are not handled.

En estadística y econometría, la prueba de Phillips-Perron (el nombre viene de Peter Phillips y CB Pierre Perron) es una prueba de raíz unitaria. Es decir, se utiliza en el análisis de series de tiempo para probar la hipótesis nula de que una serie de tiempo es integrada de orden 1. Se basa en la prueba de Dickey-Fuller de que la hipótesis nula es en , donde Δ es la primera diferencia del operador.

Webb14 dec. 2024 · Phillips and Perron (1988) propose an alternative (nonparametric) method of controlling for serial correlation when testing for a unit root. The PP method estimates the non-augmented DF test equation (42.4) , and modifies the -ratio of the coefficient so that serial correlation does not affect the asymptotic distribution of the test statistic.
