Subject   st: critical values of LBI test in xtregar

I want to check my panel regressions for first order autocorrelation using the xtregar command. Now the critical values for the Baltagi-Wu (1999) locally best invariant (LBI) test statistic are not given. Is there a way to get them? Or is it an okay approximation to use the critical values of a normal DW statistic? (Just to make sure that it's worthwhile to program the critical values.)

Many thanks,
