Dear Statalist-members,

I am exploring panel data with a long time series and want to check the
data for the existence of cross-sectional dependence applying the command
xtcsd (from scc, st0113). However, xtcsd does not work.
I noticed in earlier posts that this has been addressed already
(e.g. http://www.stata.com/statalist/archive/2009-09/msg00678.html). Since
these post are from 2009, I was wondering if there is meanwhile some sort
of remedy to this or maybe an alternative test available?

Here is what commands I performed and the error message:

firm_age _leverage_assets _rd_intensity coo_europe coo_asia

estimates store Model1_RE

. xtcsd, pesaran abs
unknown function *sqrt()

A few words on the data I am using in general: 1900 observations over 11
years.

Highly appreciate your help and comments.

Best regards,
Stefan
