Dear all

I have a problem using the Xtseial test for autocorrelation.

I have a panel data model and the xtreg command works 

tsset city year
*xtset 

xtreg a b c d, fe

xtserial a b c d


That gives 

"no observations
r(2000);"

Can you help me out?

Best

Erik

Julien--
You can just make your own graph using the variables created by -metan-:

    By default, metan adds the following new variables to the dataset:

        _ES        Effect size (ES)
        _seES      Standard error of ES
        _selogES   Standard error of log ES
        _LCI       Lower confidence limit for ES
        _UCI       Upper confidence limit for ES
        _WT        Study percentage weight
        _SS        Study sample size

and use the -xscale(log)- option and any others you like in the graph
command.

E.g.
use http://fmwww.bc.edu/repec/bocode/m/metan_example_data, clear replace
tmean=tm+10 metan tsample tmean tsd csample cmean csd, by(type_study)
gsort type_study -id g nid=_n loc o "leg(off) yti(" ") yli(10.5)
barw(.01) horiz color(gray white) yla("
forv i=1/20 {
  loc o `"`o' `i' "`=id[`i']'" "'
 }
loc o `"`o' , angle(0))"'
tw spike _UCI _LCI nid, `o' || sc nid _ES, name(notlog) tw spike _UCI
_LCI nid, xsc(log) `o' || sc nid _ES, xsc(log)
