Weighting procedures include:

¤ Use of state-of-the-art computation methods to produce sample weights
¤ Adjustments for nonresponse as appropriate; several options for doing so possible depending on the availability of information to estimate response propensities
¤ Experience with adjustment for frame coverage in telephone samples
¤ Final calibration of the weighted sample to the study population
¤ Complete documentation of all weighting methods in suitable detail for use in journal articles and analytical use of the data
