Use of multi-auxiliary variables as a condensed auxiliary variable in selecting a sample

Communications in Statistics - Theory and Methods, 1983
Information on several auxiliary variables correlated with the variable under study is available in most of the sample survey studies. This paper attempts an optimal use of several auxiliary variables in the form of a single auxiliary variable obtained as a linear function of these variables.

On improvement in variance estimation using ranks of original auxiliary variable as an additional auxiliary variable

Journal of Statistics and Management Systems, 2020
In this article, we are concerned with the utilization of ranks of original auxiliary variable as an additional auxiliary variable and thus we propose an efficient estimator of population variance....

Analysing survival in the presence of an auxiliary variable

Statistics in Medicine, 1994
AbstractA primary endpoint of AIDS trials is the length of survival. Often there is auxiliary information available on measures of disease progression, which significantly alter the risk of mortality. This paper explores the use of this information in obtaining a refined estimate of survival, and a test based on this estimate.
