Hi Dr. Muthens,

Is there any way I can get Bayesian Credibility interval at a user-defined level (instead of 95% by default)? Thanks for your help.

Not automatically. But you have access to the data behind the posterior distribution that you see in the plot and you could then find the intervals you want.

Thanks, Dr. Muthens; (1) is there any way I can save/get access the chains of values for the posterior distributions of the parameters? (I tried to look at the SAVEDATA command, but cannot get it work); (2) I was also wondering can I get access/save the bootstrap samples to an external file using Mplus 7. Thanks for your time.

1. See the BPARAMETERS option in the Version 7 user's guide.

2. No.

Then using bootstrapping, can I get user-defined confidence interval levels other than the level given by CINTERVAL (BCBOOTSTRAP) (i.e.90%, 95%,99%)? Thanks.

BCBOOTSTRAP is not available with Bayes. See pages 727-728 of the Version 7 User's Guide for a description of the intervals available with Bayes.
