Posted - 06/08/2021 : 03:30:36 AM Origin Ver. and Service Release (Select Help-->About Origin): Operating System: I am trying to fit the activation energy from temperature dependence on origin with my own function which is y=1/(1+c*exp(-E/x)), but is not fitting at all. I need to extract the constant proportionality c and activation energy E.

Posted - 06/08/2021 : 08:58:52 AM It's hard to tell why the fitting failed. It's very likely due to the initialization of fitting parameters. Please set c and E initial value close to it's true value.
