We extend the method of adaptive two-stage sequential sampling to
include designs where there is more than one criteria is used in
deciding on the allocation of additional sampling effort. These
criteria, or conditions, can be a measure of the target
population, or a measure of some related population. We develop
Murthy estimator for the design that is unbiased estimators for
the population mean, and propose another, more efficient,
estimator. We investigate asymptotic properties of this estimator.
We use a simulation study to investigate design properties of the
multi-criteria adaptive sequential sampling scheme and also some
estimator properties under the design.
