Abstract |
|
|
| Statisticians are always curious to get more precision in estimating the population parameters and this increase in precision is
achieved by using auxiliary information in survey sampling and various statisticians have used correlation coefficient, skewness,
coefficient of variation etc. as auxiliary information to get more precision, so in this paper we do the same thing by proposing the
modified ratio type estimators in SRSWOR by using the linear combination of coefficient of kurtosis and population deciles as auxiliary
information of auxiliary variable. The properties associated with the proposed estimators are assessed by mean square error (MSE) and
bias. For illustration we also provide empirical study. From empirical study it is confirmed that our proposed estimators are a class of
efficient estimators under percent relative efficiency (PRE) criterion. |
