: Population mean; Temporization effect; Auxiliary information; Ratio method; Regression method.Abstract
An important feature in estimating the population mean in sample surveys is the use of either current observations or past information, which is
available as auxiliary information. The ratio and regression methods of estimation are popular approaches for estimating the population mean using
auxiliary information. In most of these surveys, the auxiliary information is available from the past and may change over time when used. This paper
examines how this information will affect the estimation process and how the ratio and regression estimation methods are affected by such a change
in the auxiliary information.
