stratification (version 2.2-7)
Univariate Stratification of Survey Populations
Description
Univariate stratification of survey populations with a generalization of the
Lavallee-Hidiroglou method of stratum construction. The generalized method takes into account
a discrepancy between the stratification variable and the survey variable. The determination
of the optimal boundaries also incorporate, if desired, an anticipated non-response, a take-all
stratum for large units, a take-none stratum for small units, and a certainty stratum to ensure
that some specific units are in the sample. The well known cumulative root frequency rule of
Dalenius and Hodges and the geometric rule of Gunning and Horgan are also implemented.
