nlinregr non linear regression function

I created a SCILAB script and related functions to perform non linear regression of some data. I chose nlinregr because of the possibility of getting the regression coefficients. The script and the CSV file are attached.

At present, the programme is not working. Please kindly help me to make it work.

Hello Samuel,

Glad to see you on Scilab’s Discourse forum !

I have granted you level 1 so that you can add the files to your above post. We will see what’s wrong then.

I have tried to run the script attached using the nlinregr function.

Your assistance to make it work will be greatly appreciated
