quality of SE estimate by IMP method

From: Ethan Wu Date: September 16, 2010 technical Source: mail-archive.com
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.
