Abstract
AbstractProduct method of estimation (MURTHY, 1964) using supplementary information on an auxiliary variable having high negative correlation with the main variable under our study, is well known. In this paper, we propose product‐cum‐difference method of estimation for the population total and the product of population parameters when supplementary information is available on two auxiliary variables. A comparison of product‐cum‐difference method of estimation with the usual product method of estimation using single auxiliary character and the estimators by SINGH (1965) for the estimation of product of population parameters has been made along with an empirical study.
