Abstract

The ratio in finite population is one of the most common statistics used in official statistics, demographic studies, agriculture and allied field of agriculture. In this paper, estimators of the ratio/proportion in finite population are developed by incorporating known auxiliary information under the calibration approach. The variance and the estimate of variance for these estimators are obtained. A simulation study is carried out to evaluate the performance of proposed estimators comparing them with a simple estimator of the Population ratio that does not incorporate auxiliary information.
