| Abstract: | Based on the proportion estimate and the mean estimate in sampling technology, the authors of this paper put forward the method of ratio estimator in sampling technology and makes a detailed analysis of method. Through discussing some specific problems, this paper explains the superiority of the method of ratio estimator. To solve the problem of instability when the ratio of samples differ greatly, an improved formula for the method of ratio estimator is put forward by means of clustering, which can reduce the effect of noise data. In this way, better accuracy is achieved. |
