Error in structural equation model - "The model has negative degrees of freedom"
Hi
I am running a structural equation model with R using the sem command; am
getting the following error:
"Error in sem.default : The model has negative degrees of freedom = -4"
My model is as follows:
s_model = specify.model()
x1->m1, b1,NA
x2->m1, b2,NA
x3->m2, b3,NA
x4->m2, b4,NA
x5->m2, b5,NA
x6->m2, b6,NA
m1->y, a1,NA
m2->y, a2,NA
m1<->m1, v1,NA
m2<->m2, v2,NA
y<->y, v3,NA
x1-x6 are observed independent variables, m1 and m2 are the latent variables
and y...
