st: Tests for unit roots in panel data.

["Grant Peter Kabango" <g.kabango.1@research.gla.ac.uk>]

Dear Statalisters,

I am using Stata Intercooled version 9.2, and I am trying to test for unit root in panel data. In the literature, I have noted that there is 'ipshin' and 'hadrilm', perhaps among others. However, searching the help file is not producing any results.

Any suggestions as to how one may access these functions ?

Thanks

Grant
