<p>Sorry for slow reply. The provision of weights requires the ability to estimate probabilities of continuing to respond over multiple waves. This is true of cross-sectional weights as well as longitudinal ones, as they are derived from the longitudinal ones (how thi8s was done is described in section 3.8.3.10 of the User Guide). In consequence, a person in a household where there is no person who has been enumerated at every wave (up to wave 5, in your case) will get a weight of zero. Such people should not be given a weight, as the weights for all other sample members are calculated in a way that compensates for these "missing" people.</p>
<p>You should not need to apply any additional filtering to your analysis, as this is done automatically by application of the weights.</p>
