How can I fit a sigmoid line to data points using Excel or Maple?

Click For Summary
SUMMARY

The discussion centers on fitting a sigmoid curve to data points extracted using plot digitizer software. The user inquires about the capabilities of Excel and Maple for this task. While Excel may not directly support sigmoid fitting, the user discovers that Maple can effectively handle s-curve fitting. The discussion highlights the importance of using specialized software for advanced curve fitting tasks.

PREREQUISITES
  • Familiarity with data extraction techniques using plot digitizer software
  • Basic understanding of curve fitting concepts
  • Knowledge of Excel functionalities for data analysis

Hi

I used plot digitizer software to pull data points off a picture of a graph and i need to fit a line to the points (and get an equation for the line). I know the data points fit to an s-curve from the picture. I'm thinking excel doesn't do this, or maybe I missed it?

I have access to maple, can this do s-curves?

thanks in advance
