Ratio Estimators in Simple Random Sampling when Study Variable is an Attribute
Ratio Estimators Simple Random Sampling
2010/11/9
In this paper we have suggested a family of estimators for the population mean when study variable itself is qualitative in nature. Expressions for the bias and mean square error (MSE) of the suggest...

The efficiencies of the ratio- type estimators have been increased by using linear transformation on auxiliary variable in the literature. But such type of estimators requires the additional knowledge...
