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. Webb22 sep. 2024 · Specifically, the a Philips Perron estimates aimed at determining the long run relationship as well as its direction behind the long and short run causation interrelation presented by the Granger causality test. The study findings revealed that there is a long run relationship between imports and economic growth.

WebbThe null hypothesis of the Phillips-Perron (PP) test is that there is a unit root, with the alternative that there is no unit root. If the pvalue is above a critical size, then the null cannot be rejected that there and the series appears to be a unit root. http://fmwww.bc.edu/cfb/stata/TStalkJan2009.beamer.pdf

WebbBasic process is to fit the time series under test with an AR(1) model using heteroscedasticity- and autocorrelation-consistent residual covariance estimation in order to generate the Phillips-Perron Z-rho and Z-tau statistics (1988) which are asymptotically equivalent to the Dickey-Fuller (1979, 1981) rho/tau statistics. WebbThe PHILLIPS option performs the Phillips-Perron test for three null hypothesis cases: zero mean, single mean, and deterministic trend. For each case, the PHILLIPS option computes two test statistics, and (in the original paper they are referred to as and ) , …
