Good afternoon!
1 I have a bit of a problem with the Survey package, but one that is more
theoretical than practical. If for example on wishes to use some additional
information which comprises of 4 variables with 7, 5,5 and 5 categories
(resulting in 875 post-strata if the whole crossing were to be constructed) and
if only the marginal distribution of each variable is known, would it be better
to rake or to calibrate?
2 Is calibrating affected by the cells with 0 frequency, as raking is?
3 when a sample is already stratified and one wishes to post stratify by other
variables, do the new weights take account of the fact that the sample is
stratified and that sampling weights could be determined; and what is the
algorithm for determining these new weights ?
Thank you and have a good day!
