STATA example
Using the Grunfeld investment data:use "http://fmwww.bc.edu/ec-p/data/Greene2000/TBL15-1.dta"
xtset firm year
xtreg i f c,fe
xtcsd, pesaran
Output of the xtcsd command only:
Pesaran's test of cross sectional independence = 1.098, Pr = 0.2722
R example
Using the same data:library(foreign) # To import STATA .dta filesOuput of the pcdtest command:
grunfeld <- font="" read.data="">->"http://fmwww.bc.edu/ec-p/data/Greene2000/TBL15-1.dta")
pcdtest(i ~ f + c, data=grunfeld, model = "within", effect = "individual", index = c("firm","year"))
Pesaran CD test for cross-sectional dependence in panels
data: formula
z = 1.0979, p-value = 0.2722
alternative hypothesis: cross-sectional dependence
