. generate myindicator = (1/4) * I + (1/4) * II + (1/2) * III 

andreia tolciu

I want to build an additive weighted index from 3 indicators from a
survey (I have in total 2,111 observations and 61 variables). 

The form for the index can be:
 a * Indicator I + b * Indicator II + c * Indicator III 

a= 1/4
b=1/4
c=1/2

Does anyone have an idea how this would work with Stata?

Note:
(Each indicator from the 3 which I would like to use has 4 values: "1-
totally agree", "2 -I rather agree",
"3-I rather disagree", "4- I totally disagree")
