Yes, you can change the values of the parameters and then re-sum the paths
without re-fitting to give the model chi(k), chi(R), etc.
After changing the value in the Parameters (aka Guess/Set/Def) window, you
can go to the Data window and select the first option in the Action Menu
"Make sum of all paths...".
Hope that helps,
