Abstract
The sample distribution is defined as the distribution of the sample measurements given the
selected sample. Under informative sampling, this distribution may be different from the
corresponding population distribution. Sampling on two occasions under informative sampling
design, utilizing the sample and sample-complement distributions for occasion one, the matched
sample and unmatched sample distributions, and matched sample-complement and unmatched
sample-complement for occasion two, is proposed for predicting finite population total of a
variable under study for the current (second) occasion, viewing information collected on the first
(previous) occasion as auxiliary information. An interesting result of the present analysis is that
known predictors in common use are shown to be special cases of the present predictors
obtained under informative sampling, thus providing them a new justification.
