The use of auxiliary information is well-known to improve the precision of the estimate of the population mean for the study variable. We are usually interested in estimating the population mean for the variable of interest when the information of auxiliary variable(s) is considered. The auxiliary variable is correlated with the variable of interest, when is already available or can be easily observed. The ratio, product, regression and exponential (ratio, product) type estimators have been developed using the auxiliary information.
