本文提出了符合负二项分布的昆虫种群密度的一种序贯估计方法,当负二项分布的参数k已知时,估计过程非常简单。k值的精确估计是对平均密度进行精确估计的必要前提。本文给出了一种估计k值的新方法。这些方法都已广泛应用于多种害虫田间种群密度的抽样调查。
In this paper, we propose a sequential estimation method for insect population density that meets the negative binomial distribution. When the parameter k of the negative binomial distribution is known, the estimation process is very simple. An accurate estimate of k is a necessary prerequisite for accurate estimation of the average density. This paper presents a new method for estimating k-values. These methods have been widely used in sampling the population density of many pests in the field.
