Test for cross-section dependence for the Gasoline example (as in problem 13.4). Do the same for the Public Capital example. What do you conclude?

Data From Problem 13.4:

For the Grunfeld example, replicate Tables 13.6, 13.7 and 13.8, i.e., (i) obtain the Breusch and Pagan test based on the fixed effects residuals using Stata's command xttest2. (ii) obtain Pesaran's CD test based on fixed effects residuals using Stata's command xtcsd. (iii) Finally using EViews obtain the Breusch-Pagan test, Pesaran's CD test, PUY's \(L M\) test which appears in EViews as Pesaran scaled LM test, also the Baltagi, Feng and Kao (2012) Bias-corrected scaled LM test, all based on fixed effects residuals. What do you conclude?
