چکیده
|
In this paper multivariate ratio and regression estimators for estimating the population mean vector have been proposed using multi-auxiliary variables for partial information case. the expression of variance covariance matrix has been derived. empirical study has been carried out to see the performance of proposed estimator over estimator proposed by butt,et al. (2011). © 2013 pakistan journal of statistics.
