Abstract

In this study, an alternative linear combined product - ratio type estimator was proposed. This proposed estimator combined classical product estimator with classical ratio estimator. Four data sets were used to determine the efficiency of this proposed linear combined product – ratio type estimator and this proposed linear combined product - ratio type estimator was found to be better,  preferred  and efficient to all other estimators considered provided and the correlation coefficient between the study variable and variable of interest must be negative. For all the data used, the proposed linear combined product – ratio type estimator, has the least mean square error than estimator. Therefore,   is an alternative linear combined product – ratio type estimator recommended to estimator.
