Dear all,
I have a question on the interpretation of survey data.
There is a survey in which the analysis units are the households and
its members.
Using the command svyset i have set the design characteristics of the
survey: clusters, two stages, stratification and probabilistic.
And i have asked stata for the mean of the number of cars in the households.
Is it all right if i multiply the mean of the number of cars in the
households by the expanded number of households to get the total
number of cars of the households?
Or does it depend on wheter the survey was designed to get the total
number of cars of the households?
Thank you very much in advance.
Laurie
