Stata users,
is there a way to create a global list of variables that starts empty and successively adds new variables to the list as they are created? I am trying to write something like:
use "C:\XYZ.dta",clear
global Xlist
foreach var of varlist lntoen lncap lntech lndebt{
sum `var'
gen mean`var'=r(mean)
global (add the newly created variable mean`var' to $Xlist)
}
*then take the minimum of all these variables
egen Y=min($Xlist)
The reason I am trying to use a macro is because I have to create many variables and use the one that has the lowest value. This has to be done within a loop for each of several years.
Any alternative approach to mine would be really appreciated.
Many thanks
Dev
