3.99 FAQ-619 What is the difference between these two sigmoidal fitting function, Logistic and Bolzmann?

Last Update: 2/3/2015

The functional form used for a sigmoidal fit (from Analysis: Fitting: Sigmoidal Fit) depends on the X scale type.

If you are trying to fit your data to a sigmoidal fit curve with a linear X scale, the function used will be the Boltzmann fitting function.

If you are trying to fit your data to a sigmoidal fit curve with a Log10 X scale, the function used will be the Logistic fitting function.
