I've obtained different fitting results that I'm unsure how to evaluate. Below are two different fitting sets: [img]https://my.originlab.com/ftp/forum_and_kbase/Images/1e2h.jpg[/img] [img]https://my.originlab.com/ftp/forum_and_kbase/Images/2e1h.jpg[/img] My questions are: 1. How can I determine which of these two global fitting results is more reliable? 2. When multiple parameters show "Dependency" values close to 1, how should I evaluate the fitting results? 3. What is the significance of missing standard errors (shown as "--") for some parameters, and how does this affect the reliability of the results? Thanks for you help! ----------- Origin Ver. : Origin 2024b (64-bit) 10.1.5.132 Operating System: Windows 11 Enterprise Build   Check here to subscribe to this topic.
