I have the final sample weight (expansion factor) from a socieconomic
survey. I don't know the exact design used in the study ( (probably is a
stratified two-stage design).
To illustrate my problem I will use the next dataset which have a sample
weight (but the design is not specified) and incorpo
(b)=c("q99","r88","s77")
>b
q99 r88 s77
1 1 4 7
2 2 5 8
3 3 6 9
> b$q9
[1] 1 2 3
Please note that the variable q9 does not exist in the dataframe, but
you can see that R
show q9 (as q99).
Thank in advanced
Cordially
