Download Speedy Fit app from the page and install the app.
This app can be used to fit a large number of datasets from a worksheet sequentially and speedily, and create a simple report table of parameter values and fit statistics.
Fit all XY (YErr) datasets in the active worksheet
Perform linear, polynomial and nonlinear fit using different algorithms
Preview of fitted curve for current dataset with 95% confidence band and 95% prediction band
Select a built-in or user-defined function for nonlinear fit
Three choices for parameter initialization for nonlinear fit:
Initialize each dataset independently
Use fit values from previous dataset as initial parameter values for next dataset
Use custom (user-specified) initial parameter values for all datasets
Output parameter values, standard errors, dependencies etc and also output fit statistics including fit status
Output the fitted curve, and allow go through each dataset by the navigation buttons on the fitted curve graph
Use metadata elements such as long name or comments as dataset identifier in the output sheet
