Webb1 jan. 2014 · The ADF test, Phillip–Perron test, and Kwiatkowski–Phillips–Schmidt–Shin test for temperature data are presented in Table 4.2. The calculated values of the test statistics for the ADF test and Phillip–Perron test are −6.4186 and −4.3538 associated with the probabilities 0.0000 and 0.0004, respectively. 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. 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. how to shamanic journey
