A Ratio-Cum-Product Type Exponential Estimator Using Double Sampling for Stratification [PDF]

open access: yesRevista Română de Statistică, 2018
This paper proposes an improved class of ratio-cum-product type exponential estimator for estimating the finite population mean of the study variate (when sampling of study variate is costly or difficult to fetch).
