I'm trying to find the best possible fit for my data obtained in my research. I need a bit of help as I'm very new using Eureqa and I don't even know if what I want to do is possible.
The thing is: I have 504 curves which look like either of this trends (sigmoidal curves or exponential rise).
I saw some references in the literature which suggest that I should use a first order double exponential equation with an extra logistic component to account for the growth (see equation below).
I managed to write the formula and I´ve got the resultant equation but I need to see how each curve fits individually with the model as well as dependencies of the coefficients and P values. Is that possible?
You can use Eureqa's target expression to fit that exact equation form - see the documentation on setting up a custom target expression in the Eureqa Desktop product. You can put all the data you want into a single dataset to fit and plot, using a blank row between series to distinguish them as discontinuous information. Or you can copy and paste Eureqa's model into any other software (like Matlab/python) to create the exact plots that you're looking for.
