Origin Ver. and Service Release (Select Help-->About Origin): OriginPro 2020 (64-bit) SR1
Operating System: Windows 10
Hi, I have the following problem: I have four data sets (1, 2, 3 and 4) and I have a fit function with four paramters (A, B, C and D).
I know about the global fit option and how multiple data sets can be fitted together by sharing one ore more parameters. However, here the situation is the following:
All four data sets share the parameters C and D.
But for A and B Data sets 1 and 2 share values for A and B, and Data sets 3 and 4 share other values for A and B.
So, I would like to optimise A, B, C and D based on all four data sets while sharing C and D for all four data sets but sharing A and B only for each two of the data sets (1+2 and 3+4) independently.
Is there a way that can be done? |

Hi,
Can you take a look at this app? If I understand your situation correctly, this app should help. It lets you choose which parameters are shared between which functions.

Let me know if you have any more questions.
