Hi Linda and Bengt, Is there any way to retrieve the posterior estimates from MCMC estimation that are used to populate the graphs of their distribution? It would be great for manually testing hypotheses regarding the probability that a parameter is in a specific region.
You can use the BPARAMETERS option of the SAVEDATA command:
BPARAMETERS = filename;
You will get the Bayesian iterations saved into that file. It is the same information that is used to plot Bayesian posterior distribution plots and Bayesian tracelines. In Version 6.12, we show in the summary the order the parameters are saved.
Hello Prof. Muthen, I am using Bparameters to save the Bayesian parameters. However the Mplus code doesn't run when I use OUTPUT statement along with SAVEDATA: BParamaters statement? The reason I am using OUTPUT is to request for STDYX parameters as well.
For an ALT model, is it possible to save the posterior distribution of the estimated means of the time points?
I figured out how to get the posterior distribution for intercepts of the time points using BPARAMETERS but I'm wondering if you can get the estimated means (ie: those plotted in the estimated means plot)
May I just check with you that the slight differences I have in my output estimates (using Model Constraint) versus the values from the save plot data output (from the estimated means plot) are likely just rounding errors.
The plot data, which goes to 5 decimal points, shows time0 through time5 as:
