Optimum ratio estimators for the population proportion-CMMSE-10
Résumé
The problem of the estimation of a population proportion using auxiliary information has been recently studied by Rueda et al (2010), which propose several ratio estimators of the population proportion and study some theoretical properties. In this paper, we define a new ratio estimator based on a linear combination of two ratio estimators defined by Rueda et al (2010)The variance of the new estimator is calculated and it is used to obtain the optimum value into the linear combination in the sense of minimal variance. Theoretical and empirical studies show that the suggested ratio estimator performs better than alternative estimators.
