I'm attempting to run an RDSEM model with single-indicator latent variables.
As a first step, I ran a model with the latent variable loading fixed to 1 and the residual variance fixed to zero, assuming that the results would be identical to an RDSEM with observed variables. However, the estimates are all markedly different and the DIC is too large to be displayed (all asterisks).
I've copied the code below, does it look like I've missed something? Thanks!
VARIABLE: NAMES = ID TIME x; MISSING = ALL(-99); CLUSTER = ID; USEVAR = x TIME; LAGGED = x(1); WITHIN = TIME;
