比较R中的许多相关性

随着时间的推移,我有数百种人口关系(不同的物种,地点等) . 如何统计分析所有这些相关性(针对各自的群体)?

我有600个相关性中的每一个的p值,CI,相关系数,但我如何在组内(物种,位置等)比较这些相关系数 .

我试图对数据关联的人口数量(百分比)和年份进行大的部分相关,物种和位置(变成虚拟变量)作为家庭内部关联时的受控因素,以及作为受控制的位置(作为虚拟变量)在物种内相关时变量,但不确定这是否正确 .

以下是一些示例数据,但这是一个更加逻辑的问题,反对实际数据问题:

    这超出了堆栈溢出问题的范围,应该可以在更具统计意义的论坛中发布 .

    但是,我会查看 vegan 包,特别是看Canonical Correspondence分析或Principal组件分析 . 排序方法允许您减少维度并查看许多不同分组变量之间的重要/有用的相关性 .

    将时间序列作为模型中的变量之一,确定是否存在与重复集合相关的影响在统计上是正确的 . 多因素ANOVA在确定变量之间的相关性方面可能比在排序方法中找到点组更有用 .
