st: panel data -xttest2 and xtpcse modules

Dear Statalisters,
I am using an unbalanced panel data set and would like to test whether
there is cross sectional correlation of the residuals using xttest2.
However I obtain the following message:
"too few observattions across panels. no observations"
Also, when trying to estimate a panel corrected std error model (xtpcse)
using the pairwise option the t statistics are missing.
Could anyone give me some advice on this please?
Many thanks for your help,
Lola
