对于分层随机抽样总体均值的估计，本文提出了一种比组合比和分离比估计更有效的组合乘积估计。此外，所提出的估计量的偏差和均方误差的精确表达式。最后给出了一个实例来比较不同估计量的有效性。
For the estimation of the population mean in stratified random sampling a ‘Combined Product Estimator’ is proposed which is more efficient than the ‘Combined Ratio’ and ‘Separate Ratio’ estimators. Also, the proposed estimator have exact expressions for bias and mean square error. An empirical illustration is given to compare the efficiencies of different estimators.
