Estimation of Domain Mean Using Two Stage Sampling in the Presence of Nonresponse Aditya Kaustav* *Indian Agricultural Statistics Research Institute, New Delhi Online published on 28 July, 2016. Abstract The problem of estimation of domain mean under random response mechanism has been considered when the sampling design is two-stage with two phases at the second stage. A estimator is developed based on the technique of sub sampling of non-respondents. Expressions for the variances of the estimators are developed. Optimum values of sample sizes are obtained by considering a suitable cost function. The percentage reduction in the expected cost of proposed estimators is studied empirically. Top Keywords Cost function, Optimum values, Random Response, Nonresponse, Sub-sampling, Two-stage sampling. Top | |
