Dear Statalist, 
as I didn't find a satisfying answer in the archive, I post my question here:
How do I know which lag to look at at the kpss test results? For example with this one ...
KPSS test for lnbrd
 
Maxlag = 8 chosen by Schwert criterion
Autocovariances weighted by Bartlett kernel
 
Critical values for H0: lnbrd is trend stationary
 
10%: 0.119  5% : 0.146  2.5%: 0.176  1% : 0.216
 
Lag order    Test statistic
    0           .318
    1           .178
    2           .135
    3           .118
    4           .111
    5           .109
    6            .11
    7           .113
    8           .118
_______
varsoc lnbrd yiels lags=3.
Thanks for your help!
Barbara
