I am applying structural equation modeling on ecological data.
(我正在对生态数据应用结构方程模型。)
However, then I run the code the error "Model is recursive. Remove feedback loops!". (但是,然后我运行代码,错误为“模型是递归的。请删除反馈循环!”。)
I have drawn the structural model to find the recursivity, but haven't discovered the problem yet. (我已经绘制了结构模型以找到递归,但尚未发现问题。)
library(piecewiseSEM)
dSep(psem(
lm(y1 ~ x2 + x3 + x1, data = dat.2),
lm(y2 ~ y1 + x3 + x1, data = dat.2),
lm(x3 ~ x1, data = dat.2)
))
The problem lies in the linckage between x3 and y1, but removing this path leeds to a significant Fisher's C test using the original data.
(问题出在x3和y1之间,这点很麻烦,但是删除该路径会导致使用原始数据进行重大的Fisher C测试。)

Can anybody tell me, how to avoid the feedback loop? (谁能告诉我,如何避免反馈循环?)
Thanks, Martin
