Hello all,
I have been experimenting with svymean() and I am confused on what the
output is. The data I have looks like:
*PSU*
* STRATUM*
* WEIGHTS*
* COUNTS*
*1*
1
1
2.0
1
*2*
2
1
1.0

*3*

*7*

*8*

3.0

I have this code:
> q<-data.frame(PSU,STRATUM,WEIGHTS,COUNTS)
> View(q)
> dd<-svydesign(id=~PSU,strata=STRATUM, weights=~WEIGHTS, data=q,nest=TRUE)
> svymean(~COUNTS,dd)
mean SE
COUNTS 1.2222 0.1607
I thought that SE was the standard error. When I tried to calculate it by
hand I got something different. What is SE and how is it calculated? Thank
you in advance!
