You should note that the critical values reported by eviews are valid only for unit root tests of a data series, and will be invalid if the series is based on estimated values.

For the first question, i think they are test statistics based on different panel data methods for testing cointegration relationship. You may wish first to apply unit root tests to each series in the var. Variables must exhibit cointegration to be used here. Most of the economic indicators are nonstationary o using the unit root test also prevents the spurious regression problem. If you look at the help file of xtpedroni, you will find that the result table contains 7 test statistics of pedronis 7 panel data models for testing. The results indicate also that there is no significant granger causality from fdi to economic growth, from economic growth to fdi, from trade to economic growth and from economic growth to trade in the short run. Please include your serial number with all email correspondence. Therefore, a test of the null hypothesis of no cointegration. However, when the two test results vary, you should apply the pantula principle, i. After discussing cointegration test results subsection 5.

The englegranger and phillipsouliaris residualbased tests for cointegration are simply unit root tests applied to the residuals obtained from sols estimation of equation 27. Regarding the test results, note that eviews computes both the englegranger taustatistic tstatistic and normalized autocorrelation coefficient which we term the zstatistic for residuals obtained using each series in the group as the dependent variable in a cointegrating regression.
