How do I perform a stretched exponential curve fit?
Stretched exponential curve fits:
- Equations of the form: y = 1 – exp[ -(t / tau)^b]
- This can cause a problem because KaleidaGraph could be trying to take a root of a negative value.
- To solve the problem, rewrite the equation as: y = 1 – 1 / [exp((t / tau)^b)]
