I thought it should work with my old code, but apparently, I am doing something wrong, but I don't see my mistake Excel retuns an exponential function of 150e-0.115x, so I For instance, parabolic part of the logistic function has to be a bit stronger (neds to increase a bit faster), while exponential part of the sigmoid curve should increase slower. To sum up the steps: Open NLFit dialog box (Ctrl + Y) For function select 'new ' and follow dialog Select 'Explicit' and 'Expression', press 'Next' Set y_0, ka, and x_c as parameters and add a as constant. The application offers an easy-to-use interface for beginners, and the ability for advanced users to customize analysis and graphing tasks using themes, templates, custom reports, batch processing and programming. In this video, I will teach you about an exponential fitting to the experimental data with originlab 2021. Click Next to go to Name and Type page, select PFW category from Select or create a Category drop-down list, input MyPeakFunc as Function name. // For example, if you want to fit with functions from the NAG library, // add the header file for the NAG functions here. The fitting function is the following: y = V + (A-V)*S*x*EXP(-S*x) where V, A and S are the parameters which I need to calculate from the fit. The point is that we reached a better fit than OriginLab - the residuals are lower. It can find the optimal model by AIC, BIC, Adj.
