近两年,我们对典型中心抽样概率分布进行了专题研究,目前已获得初步成果,现摘要于后,供有关同志参考。“典型中心抽样”是沈阳农学院谭启栋教授于一九七八年提出的一种简易调查方法。其原理是利用概知的总体,典型的抽取接近概知平均数的少量样本,并以其实测值估计总体参数。方法提出后,立即引起许多数理统计专家与广大调查人员的重视。辽宁林勘院、南京林学院、广西林勘院等单位的科研工作者除进行实际试验外,还进行了有关理论方面的研究。
In the past two years, we conducted a special study on the probability distribution of typical center sampling, and now we have obtained preliminary results. The summary is now available for reference by the relevant comrades. Typical Central Sampling is a simple survey method proposed by Professor Tan Qidong of Shenyang Agricultural College in 1978. The principle is to use the general knowledge of the typical extraction approximate to the average of a small number of samples, and the actual measurements to estimate the overall parameters. After the method was put forward, it immediately caused the attention of many mathematical statistics experts and the majority of investigators. Researchers from Liaoning Forestry Research Institute, Nanjing Forestry College, Guangxi Forestry Research Institute and other units carried out the theoretical research in addition to the actual experiments.
