After struggling with my data in the stage 1 of TSSEM, I finally moved into the stage 2. However, the output seems not to be very good.
(1) The results of two approaches of specifying models are different.
Specifically, when using "diag.constraints=TRUE, intervals.type="z"", the result suggests "Amatrix[1,22]" and "Amatrix[1,23]" are significant. But removing the "constraints" and "intervals.type", the result suggests "Amatrix[1,21]" is significant.
In addition, both results have same goodness-of-fit values. Which result I should believe?
(2) the Goodness-of-fit index is not satisfied.
Although RMSEA and SRMR are OK and OpenMx status1 is "0", both TLI (0.5361) and AIC (0.5971) are much lower than 0.95. Is there anything wrong with my model or my stage-1 data?
Thanks in advance!
p.s., I enclose the output for your reference.
