Hi all,
I am trying to create a custom function to fit a set of data to, but the fit is just producing a straight line. I do not know what I'm entering wrong.
The function I want to fit to is y=-log10((10^-A*x)+B) where y is the dependent variable, x the independent, and A and B are parameters. I don't know if my equation syntax is wrong, or what the problem is. |

Hi,
Please use the expression:
y=-log((10^-A*x)+B)
See if it works.
