On this run:

The "Bigger" and "Smaller" options on the Estimation pull-down menu may be helpful.

Press Ctrl+F to force an iteration to cease, and fit computation to begin.

 

On later runs:

1) Specify the final values from previous runs as the starting values for new runs. This can be done by generating an anchor file from each run, and then use this as the specification file for the next run, after removing all ",A" anchoring flags.

See Labels= and Rating (or partial credit) scale= for further information on starting values.

 

2) Specify liberal convergence criteria, particularly if this is an exploratory analysis to see whether things make sense, e.g., "Convergence=1,.1"

 

3) Do not specify output that you don't really want, e.g., do not specify "Inter-rater=" (rater agreement) unless you need it.

 

4) Specify "Subset detection=No" once subset
