--- On Mon, 8/2/10, Kelvin Tan asked: > I would like to know if I can stack two correlation matrix > tables into one big correlation matrix (("foreign=1") in > lower diagonal and (foreign=0) in upper diagonal of the > big correlation matrix table) . I gave a solution that worked for just the correlation coefficients but which could not report any stars, standard errors, p-values, or confidence intervals. Ben Jann just answered me privately with an example of how to do the latter, which I am forwarding below. Hope this helps, Maarten --- Ben Jann: here is some code if you just want to stack two correlation matrices: eststo clear sysuse auto local vlist price mpg weight foreach v of local vlist { estpost correlate `v' `v' `ferest()' if foreign==0 foreach m in b rho p count { matrix tmp = e(`m') matrix coleq tmp = "foreign=0" matrix `m' = tmp } estpost correlate `v' `v' `ferest()' if foreign==1 foreach m in b rho p count { matrix tmp = e(`m') matrix coleq tmp = "foreign=1" matrix `m' = `m', tmp } ereturn post b foreach m in rho p count { quietly estadd matrix `m' = `m' } eststo `v' } esttab, nonumbers mtitles noobs not (Note that `ferest()' expands to the unprocessed elements of the foreach loop.) The lower/upper triangle thing is more difficult. Let's see ... Here's a solution: eststo clear sysuse auto local vlist price mpg weight local upper local lower `vlist' foreach v of local vlist { estpost correlate `v' `lower' if foreign==1 foreach m in b rho p count { matrix `m' = e(`m') } if "`upper'"!="" { estpost correlate `v' `upper' if foreign==0 foreach m in b rho p count { matrix `m' = e(`m'), `m' } } ereturn post b foreach m in rho p count { quietly estadd matrix `m' = `m' } eststo `v' local lower: list lower - v local upper `upper' `v' } esttab, nonumbers mtitles noobs not -------------------------- Maarten L.
