Asunto: st: help with xtserial
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)
