[英]Comparing many Correlations in R
隨着時間的推移,我有數百種人口(不同物種,位置等)的相關性。 如何統計分析所有這些相關性(針對它們各自的組)?
對於600多個相關性中的每一個,我都有p值,配置項,相關系數,但是如何在組(物種,位置等)中比較這些值。
我嘗試對與人口數量(百分比)和年份相關的數據進行大的部分相關,在家庭內部進行關聯時將物種和位置(轉換為虛擬變量)作為受控因素,而將位置(作為虛擬變量)作為受控因素在物種內部進行關聯時會產生變量,但不確定是否正確。
這是一些示例數據,但這是一個與實際數據問題相反的邏輯問題:

任何建議表示贊賞,謝謝!
這超出了堆棧溢出問題的范圍,可能應該發布在面向統計的論壇中。
但是,我將檢查vegan
軟件包,並專門研究規范通信分析或主成分分析。 類似的排序方法使您可以減少維數,並查看許多不同分組變量之間的重要/有用關系。
將時間序列作為模型中的變量之一,從統計角度上確定在時間上是否存在與重復收集有關的影響是正確的。 與確定排序方法中的點組相比,多方ANOVA在確定變量之間的相關性時可能更有用。
