【摘要】：用樣本推斷總體,權(quán)數(shù)的作用十分重要。通過(guò)權(quán)數(shù),不僅能將樣本還原到總體,還能調(diào)整樣本的結(jié)構(gòu),從而提高估計(jì)的精度。但權(quán)數(shù)也是把雙刃劍,如果調(diào)整后的權(quán)數(shù)差異過(guò)大有可能增大樣本量的方差。本文從權(quán)數(shù)控制的角度出發(fā),利用權(quán)效應(yīng)對(duì)主觀截取和計(jì)算截取兩種權(quán)數(shù)控制方法進(jìn)行對(duì)比研究。最后得出,主觀截取對(duì)權(quán)數(shù)的控制要稍?xún)?yōu)于計(jì)算截取的效率,并且得出若采用主觀截取、計(jì)算截取的方法,?(28)0.05、?(28)0.95可分別作為一般的分割點(diǎn)。
[Abstract]:It is very important to infer the population from the sample. Through the weight, the sample can not only be reduced to the population, but also the structure of the sample can be adjusted, so as to improve the accuracy of the estimation. However, the weight is also a double-edged sword, if the adjusted weight difference is too large, it is possible to increase the variance of the sample size. From the point of view of weight control, this paper makes a comparative study on subjective interception and computational interception by using weight effect. Finally, it is concluded that the control of the weight of subjective interception is slightly better than that of calculating interception, and it is concluded that if subjective interception is used, the method of subjective interception can be used as the general dividing point of? (28) 0.05 and? (28) 0.95 respectively.
