请问各位这到底是怎么回事？
An error occurred while attempting to fit the model
Either the constraints on the parameters or the initial parameter values are bad.This error can occur,for example,if you request a maximum likelihood solution while specifying initial parameter values that population covariance matrix from being positive definite.
Check to make sure that every endogenous variable has a residual variable (error variable)associated with it.
