r - R中的pSEM：错误“模型是递归的。 删除反馈循环！”返回(pSEM in R: Error “Model is recursive. Remove feedback loops!” is returned)

Question

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。)

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。)

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
