XTCD: Stata module to investigate Variable/Residual Cross-Section Dependence

The xtcd command implements the Pesaran (2004) CD test for cross-section independence in macro panel data. It builds on the existing xtcsd command by De Hoyos and Sarafidis (2006), but is not an post-estimation command. Instead the routine allows for the analysis of cross-section dependence in any variable and residual series specified. Furthermore it allows for the computation of the CD test as well as averaged correlation and absolute correlation coefficients for up to nine series at a time, thus representing a useful extension of the xtcsd command.
