which panel unit root tests are suitable for heteregenous panels with cross-section dependence?

[Anita Hasli]

pescadf runs the t-test for unit roots in heterogenous panels with cross-section dependence, proposed by Pesaran (2003).xtcips estimates the CIPS test for unit roots in heterogeneous panels developed by Pesaran (2007; Section 4, p. 275-279). what is the difference in these two tests? would Hadri test be good too for heterogenous panels with cross section dependence? the data being examined are developing countries from different regions in the world. can someone help me with this issue?
