st: RE: Estimate variance from the California Health Interview Survey usi ng STATA
I am trying to anlayze the California Health Interview Survey using STATA
8.0. The CHIS contains a basic weight variable that can be used to obtain
However, to estimate variances you need to use replicative weights- 80
weights are provided. Estimates of variance using the replication method can
be obtained using
WesVar or SUDAAN.
But how can you estimate variance using these weights and STATA??? Is it
impossible? The Public Use Data File has no strata info or PSUs.
