古湖泊学中的分析方法包括现代类比技术（MAT），作为从代用地层生物数据定量重建过去环境的一种手段，以及类比匹配（AM），作为比较化石组合与现代组合的一种手段，为环境保护和退化湖泊的恢复提供信息。MAT的数学和MAT的性能统计的空间自相关的问题进行审查。使用一个或多个代理（例如，硅藻，枝角类）和选择适当的相异措施进行了讨论。各种方法来回答的问题，有多少类似物（k）应该用于环境重建或恢复目标的设置进行了讨论。这些措施包括优化一些误差函数，如预测的均方根误差，寻找“跳跃”的相异值，检查所有现代相异的参考分布，蒙特卡罗回归，构建受试者工作特征（ROC）曲线，并应用逻辑回归分析。使用类似匹配作为一种工具，以帮助评估古环境重建概述。合适的软件和未来的工作方向进行了讨论。
Analogue methods in palaeolimnology consist of the modern analogue technique (MAT) as a means of reconstructing quantitatively past environments from proxy stratigraphical biological data and analogue matching (AM) as a means of comparing fossil assemblages with modern assemblages to inform environmental conservation and restoration of degraded lakes. The mathematics of MAT are presented and problems of spatial autocorrelation on MAT’s performance statistics are reviewed.Analogue matching using one or more proxies (e.g., diatoms, cladocerans) and the choice of appropriate dissimilarity measures are discussed. Various approaches to answering the question how many analogues (k) should be used for environmental reconstructions or to set restoration targets are discussed. These include choosingkto optimise some error function such as root mean squared error of prediction, finding ‘jumps’ in the dissimilarity values, examining the reference distributions of all the modern dissimilarities, Monte Carlo resampling, constructing Receiver Operating Characteristic (ROC) curves, and applying logistic regression analyses. The use of analogue matching as a tool to help evaluate palaeoenvironmental reconstructions is outlined. Suitable software and directions for future work are discussed.
