I wonder whether Mplus supports the specification of the starting values for all estimated parameters? I plan to examine the effects of different sets of starting values on the estimation accuracy, which requires to manipulate the starting values of all parameters to specific values, e.g., a set of extreme values for the parameters to be estimated, or a random sampled from a specific parameter space.
If so, where can I find reference on how to achieve that? The closest syntax identified was the "STARTING =" under the MONTECARLO command. Yet it is insufficient information to achieve the goal.
If not, the follow-up question is that does the permutation of the starting values supplied by Mplus use the same seed for each estimation? In other word, if I replicate one estimation multiple times without specifying any seed for starting value, will the estimation process and results be exactly the same?
Yes, you can specify starting values for each parameter to be estimated. Note that each example in the User's Guide has a corresponding Monte Carlo version on our website - this shows how you give starting values.
