Looking for some help in using the "survey" package
I have gone through the documentation but still find problems in understanding how to prepare my data to be analyzed wih this package.
In particular I dont understand how to prepare the fpc data.
The documentation provides a "small survey example" where 6 variables are given:
stratid,psuids,weight,nh,Nh and x
My survey is a two stage stratified sampling so I have for each stratum the number of primary
and secondary units in the sample and in the population, and using these data I can prepare such
data frame, except for the last variable "x".
I cant understand what does it means and which information I have to put there.
A second (minor) problem is that my stratification is based on two variables, but it looks like it is only possible to give 1 variable as strata parameter.
Is it possible to give two ?
