Hello;
 
Our survey is structured as : To be investigated area is divided into 6 regions, 
within each region, one urban community and one rural community are randomly selected,
then samples are randomly drawn from each selected uran and rural community.  
 
The problems is that in urban/rural stratum, we only have one sample. 
In this case, how to do bootstrap?
 
Any comments or hints are greatly appreciated!
