output for linear mixed models

[Paola Chivers-2]

Hi,



When I run a linear mixed model the following style of output occurs (see
sample below).



Estimates of Fixed Effects(b)






Parameter

Estimate









Intercept

12.733534


[Sex=0]

-.592242


[Sex=1]

0(a)





How can I change the model specifications for my outputs so that the first
variable is always zero?

(see below).






Parameter

Estimate









Intercept

12.733534


[Sex=0]

0(a)


[Sex=1]

.592242







Regards,

Paola

In SEM, the errors are considered latent variables.  AMOS software used either ellipse or circle to represent a latent variable.  What is the implication of correlated error terms?

  Thank you.

That would depend on which errors are correlated. If they are
disturbance terms (a more correct term than error) between indicators
for a latent variable then they imply something more complicated in your
measures that a simple latent variable. On the other hand, correlation
between disturbance terms for endogenous latents are less likely to be
questioned.
