Re: [NMusers] quality of SE estimate by IMP method

2010-09-16 Thread Ethan Wu
Hi Bob,
  Is there a way to pick up from the last run with SAEM/IMP so to only run the 
additional step IMPMAP?
Thank you.

At this point the SE may be unreliable.  Try using IMPMAP (and EONLY=1) and see 
if that helps.  Let it run for 20 iterations.

Dear uses,
  I am using NM7 SAEM method for an analysis. As I learned from NM7 workshop, I 
used IMP method after SAEM to generate SE estimate.
  In this case, at the end of SAEM iteration, OBJ was quite stable and negative 
several thousand.
  But, with IMP, after 5 iterations, Obj was up to positive several 10 to power 
of 7. Obj was decreasing during this 5 iterations.
  My questions is, dose this mean SE estimate is not reliable? Should I 
increase 
iterations of IMP?
Thank you.

Yes.  Read the METHOD=CHAIN section in the intro712.pdf manual.
