Dear statalist,
I have to make this operation:
gen capscore= quality+newequip+intrd+skilltrai+skilled+edu+traiprog
I have several missing values in the different variables.
I would like to proceed with the sum (forgetting missing values), what may
I do?
For instance, if I have one of the 7 variables that have missing values, I
woul like to see the result of the sum of the other 6.
Thanks and regards,
Alejandra Molina
