Hi everyone,
I would like some package of R or any help to solve the next problem
with a weighting fatcors:
Giving a data matrix with dichotomous (2 or more) variables in columns
and individuals in rows, and also a theorical distribution of the
dichotomous variables I would like a row weight (one per individual)
that transform the real distribution of variables to the theorical
distribution.
You should be able to do this with postStratify() in the survey package
(if you have joint distributions for the variables) or calibrate() if you
have only marginal distributions.
You would need to create a survey design object, use postStratify() or
calibrate() on it, then use weights() to extract the weights.
