st: should estat sd reports same sd before and after clustering?

[Afia Tasneem <afiata@gmail.com>]

Dear all,

I am working on the analysis of a clustered randomized trial.

My standard errors change when I svyset the data to account for
clustering. However, the standard deviations after clustering with
svyset and using estat sd is the same as before clustering (also the
same as simply using: sum var). Should the sd remain unaffected with
changes in se due to clustering? Or is the command "estat sd" not the
right one to use to find standard deviations after clustering?

Thanks much,
Afia
