Justus,
You need to specify the purpose of the weights. Are these sampling weights (inverse
of the probability of selection) post-stratification weights (to correct for sampling
proportions of the Census), weights to be used for boosting regression,weights to
downweight outliers, or weights for weighted least squares designed to address a
problem of heteroskedasticity, weights to address edge effects in spatial statistics?
In these cases, the type of weight to be used could be based on a different formula.
