I'm trying to do some confirmatory factor analysis on some data. My SEM
model solves in 22 iterations, but when I try to look at the modification
indices, using mod.indices, I get the following error message:
Error in solve.default(hessian) :
system is computationally singular: reciprocal condition number =
4.40283e-18
What does this mean?
Many thanks,
Dan
