Abstract

The advantages and disadvantages of statistical methods for estimating the age of animals that lack recording structures are discussed in the article. The discussion is supported by examples from studies on the growth of the bivalve mollusk Mizuhopecten yessoensis (Jay, 1857). The age of individuals of this species can easily be determined by morphological marks on the shell surface. This makes it possible to calculate the percentage of erroneous age estimates through various statistical procedures. The following methods have been comprehensively tested: building a histogram, cumulative frequency curve, and dendrogram, as well as K‑means. The algorithms that form the basis of these methods are described in brief. Some practical recommendations on their use are provided.

基于计算机的动物年龄估算方法的比较

摘要

本文讨论了用于估计缺乏记录结构的动物年龄的统计方法的优缺点。来自双壳软体动物Mizuhopecten yessoensis（Jay，1857）生长研究的实例为该讨论提供了支持。可以通过壳表面的形态标记轻松确定该物种的年龄。这样就可以通过各种统计程序来计算错误年龄估计的百分比。以下方法已经过全面测试：构建直方图，累积频率曲线，树状图以及K均值。简要描述了构成这些方法基础的算法。提供了一些实用的建议。
