我有数百个种群(不同的物种、位置等(随时间变化的相关性。如何统计分析所有这些相关性(针对它们各自的组(?
我有 600+ 相关性中每个相关性的 p 值、置信区间、相关系数,但我如何在组内比较这些(物种、位置等(。
我试图对与种群数量(百分比(和年份相关的数据进行大的偏相关,当在家庭内相关时,物种和位置(变成虚拟变量(作为控制因素,当在物种内相关时,与位置(作为虚拟变量(作为受控变量,但不确定这是否正确。
以下是一些示例数据,但这是一个与实际数据问题相反的更后勤问题:

任何建议不胜感激,谢谢!
这超出了堆栈溢出问题的范围,可能应该发布在更面向统计的论坛中。
但是,我会查看vegan
包,并专门研究规范对应分析或主成分分析。 像这样的排序方法允许您降低维数并查看许多不同分组变量之间的显着/有用的相关性。

将时间序列作为模型中的变量之一,确定是否存在与随时间变化的重复集合相关的效应在统计上是正确的。 多向方差分析在确定变量之间的相关性方面可能比在排序方法中查找点组更有用。
