G. M. Oyeyemi, I. Muhammad & A. O. Kareem · Asian Journal of Probability and Statistics · 2023
A family of exponential-type estimator for estimating population mean in two-phase sampling when the population proportion of the auxiliary character is available is proposed in this paper. Theoretically, the bias and minimum mean square error (MSE) for the proposed estimator are...
