We has a similar thread a couple of weeks ago
http://www.stata.com/statalist/archive/2009-04/msg00539.html 
where critical values were missing because the literature had simply not
tabulated them. I suppose that could be the issue here, too, as the help
file says: 

" The critical values for nharvey for the constant and trend case are
tabulated
in NH, 2000."

BTW, you should say where you obtained this command as it is not part of
official Stata...

Betreff: st: nharvey with no critical value

Dear statalists,

I have conducted panel unit root test using nharvey and obtained no
critical values as below.
Can anybody kindly let me know what is the problem with my data?

Thanks in advance.

YK

nharvey pst if ind_short2==3

Nyblom-Harvey (2000) statistic for pst
Deterministics chosen : constant
H0: 0 common trends among the 487 series in the panel
Critical values for N=     .
                    10%         .
                     5%         .
                     1%         .

Assuming IID RW errors :             3.9231

With nonparametric adjustment
for long-run variance (2 lags) :     2.7310
