st: Re: Unit root tests for unbalanced data panels in Stata

[Kit Baum <baum@bc.edu>]

Dear Jean
This question comes up from time to time on Statalist. I do not believe 
that any of those routines will work with unbalanced panels. Some of 
the underlying analytics for some of the tests may be compatible with 
unbalanced panels (or at least timeseries without gaps) but none of the 
routines {hadrilm, ipshin, levinlin, madfuller, nharvey} are 
implemented to allow for unbalanced panels.
Thanks
Kit Baum
