FUQUENE P, JAIRO ALBERTO and BAUTISTA, JAIME LEONARDO. El diseño P.P.T. con variables categóricas para la estimación de dico-razones. Rev.Colomb.Estad. [online]. 2005, vol.28, n.1, pp. 99-112. ISSN 0120-1751.
In probability proportional-to-size designs (P.P.S.) the selection probabilities that minimize the approximate variance of a totals ratio for dichotomic variables - dicho-ratio are found and their efficiency is compared with respect to S.I. design.
