An improved estimator for the population mean using additional information
Kumar, M1, Singh, R2, Adewara, A.A3.
An improved estimator that made use of information on auxiliary variables and variables of interest which was not drawn up yet was proposed to estimate the population mean of the variable under study. Under simple random sampling without replacement, the mean square error up to the first order of approximation was derived. An empirical study was also carried out to show the properties and efficiency of the proposed estimator.
