Abstract |
|
|
| This paper addresses the problem of estimating the population mean in the presence of auxiliary information when study
variable itself is qualitative in nature. Bias andMSE expressions of the class of estimators are derived up to the first order approximation.
The proposed estimators have been compared with the traditional estimator and several other estimators considered by [15]Singh. In
addition, we substantiated this theoretical claim by an empirical study to show the superiority of these estimators. |
