XTWEST: Stata module for testing for cointegration in heterogeneous panels
AbstractThe xtwest command implements the four panel cointegration tests developed by Westerlund (2007). The underlying idea is to test for the absence of cointegration by determining whether there exists error correction for individual panel members or for the panel as a whole. The tests are general enough to allow for a large degree of heterogeneity, both in the long-run cointegrating relationship and in the short-run dynamics, and dependence within as well as across the cross-sectional units. The routine is described in Persyn and Westerlund (2008), Stata Journal 8 (2), 232-241. The routine relies upon N.J. Cox's -matvsort- routine, which is included in the package.
