The Construction of a Self-Representing Stratum of Large Units in Survey Design

Approximate cut-off rules for stratifying a population into a take-all and take-some universe have been given by Dalenius (1952) and Glasser (1962).Their cut-off value (the value that delineates the take-all and take-some boundary) was derived on the assumption that all units from the take-all universe were included in the sample and that a simple random sample of fixed size was to be drawn without replacement from the population of take-some units.In the present context, exact and approximate cut-off rules are worked out in terms of required precision expected from the overall sample.
