Oggetto: st: if and if
Hello everyone,
I realize that there are 2 kinds if's in Stata.
Type 1 : would be something like replace j = 2 if k==2
here the replace in j would happen ONLY in the corresponding
observation of k. THIS IS WHAT I WANT.
Type 2 : the programming if something like
local j
if `j'==2 {
do something.
}
**************************************************************
I guess I want to do something which is in between the above 2.
I want to say the following : --
replace j=2 if k==2
replace m=2 if k==2
replace n=2 if k==2
in ONE shot.
so I try : -
************************************** Block A
if k==2 {
replace j=2
replace m=2
replace n=2
}
*********************************************
This does not work. Because k==2 would mean k==2 in ALL observations.
While I mean to say make j / m / n = 2 in those observations where k
is 2.
How do I do this in a quick manner in Block A ?
I understand that I can always do :-
foreach var of j m n {
replace `var'=2 if k==2
}
But is there a better way ?
The reason I want this is the following : -
I want
if k==2 {
replace j=1
replace m=5
replace n=89
}
so the above method fails as I do not have the SAME value 2 to be put
in each of j / m /n.
Any slick way of doing this ?
Thank you,
Ashim
