st: IVREG2 and AR(1) Correction

["John A Karikari" <KarikariJ@gao.gov>]

I am using the IVREG2 procedure to estimate a panel model with
instruments and clusters.  The procedure does not have an AR(1)
correction, but test indicates that the residuals are AR(1).  I'll
appreciate any insights.  Thanks in advance.
