Donde Esta Lisrel? http://www.ssicentral.com/
be forewarned: Lisrel is not Mac-friendly
You can download a “free 15 day trial edition”
(the program has everything, but it goes “poof”
in 2 weeks), or you can download a “free
student edition” (which remains accessible
forever but has truncated options, e.g., fewer
variables are allowed, etc.):

The Lisrel Model
Measurement Model:
Structural Model:
y   y  
x   x  
  B    
Definitions:
y is a vector of observed indicators of the dependent latent endogenous variables
x is a vector of independent, or exogenous, variables
Λy is the factor loadings of y on η
Λx is the matrix of factor loadings of of x on ξ
η is a vector of latent dependent, or endogenous constructs
ξ is a vector of the independent latent variables, exogenous constructs
ε is vector of measurement errors in y
δ is vector of measurement errors in x
Γ is a matrix of coefficients of the ξ’s on the η’s (the structural relationships)
B is a matrix of coefficients of the η’s on η’s (the structural relationship)
ζ is a vector of equation errors (random disturbances) trying to predict the
endogenous guys η (the structural relationship errors)
