摘要：
This study proposes a new class of regression cum ratio estimators, using transformation of the auxiliary variables. The expressions for the biases and mean squared errors of the new class of estimators are derived in the study. Both the theoretical and numerical comparison of the proposed estimators and their respective competitive estimators are made. To check the performance of estimators, a simulation study was performed. The performance of the new class of estimators was assessed and proven better in comparison to their competitive estimators.
