Dr. Fournier.
Your help and advice are more than great!!!   Based on your tips, I
modified a little: e.g.,

  init_bounded_number log_avg_F(-5.0,0.4,6);   //instead of
init_number log_avg_F

  int nsteps=8;   //increasing the nsteps more

Then, the estimation is successful and the results all are
reasonable.   Thank you VERY MUCH.  Best Wishes.
