Survey - Cluster Sampling
...clusters?
3. How do I work with weights correctly? I understand that weights imply
inverse probability weighting 1/p with p=n/N in simple sampling, in
our case 72/9=8, because I sample 9 units out of a total population of
72. Again, I couldn't tell survey the number of total clusters M. So:
dclus3<-svydesign(id=~cluster, weights=~weight, data=clus1, fpc=~N)
svymean(~y, dclus3)
mean SE
y 44.778 0.2878, still exactly the same numbers, although I provided the
weights. What am I doing wrong?
I am sorry to bother you. Studying Statistics isn't done in a day,
that's for sure...
