About this Resource

Suppose that you are interested in whether the correlation between trust in politicians (trstplt) and generalized trust in other citizens (ppltrst) is stronger in some countries than others, in Stata the relevant command would be.

bysort country: pwcorr trstplt ppltrst, star(5)

------------------------------------
-> country = AT

             |  trstplt  ppltrst
-------------+------------------
     trstplt |   1.0000
     ppltrst |   0.1572*  1.0000

-> country = BE

             |  trstplt  ppltrst
-------------+------------------
     trstplt |   1.0000
     ppltrst |   0.3635*  1.0000

-------------------------------------
-> country = CH

             |  trstplt  ppltrst
-------------+------------------
     trstplt |   1.0000
     ppltrst |   0.2297*  1.0000


This will list the correlation coefficient between trstplt and ppltrst for each value of the variable 'country', and place an asterix by those that are statistically significant at the 5% level.
