Dear statalist users,
I am trying to run a multilevel modelling clustering at the individual
level (there are several responses from 1 individual that might be
correlated) and adjusting for complex survey data in Stata 10. The command
I am using is:
svyset province [pw = weight], strata(region) fpc(fpc)||ID, fpc(fpc2)
where:
SU1: province
fpc: number of provinces within each region
SU2: individual (ID)
fpc2: number of individuals within each region
I get the following error message from Stata:
Note: missing standard errors because of stratum with single sampling unit.
Could anyone give me some advice on this? Thank you very much in advance
