LybraFit

Mathematicians and people who require the use of regression in their research or work will often resort to quite complicated software for performing such operations. LybraFit aims at providing an accessible and at the same time effective tool for inputting data, tabulating it, plotting its least square regression graphs and exporting the results.

Users have the choice of either inputting the data manually or importing it from text files, and the program will provide a useful content preview. This feature enables people to view the original content of the data and the parsed version.

The application comes bundled with a library that contains a series of predefined models for classic functions such as Cos, Exponent, Gaussian, Harmonic, etc.; each of the functions has its formula displayed in the description.

Once the preferred data has been inputted or imported, one can then proceed to plot the modeled information, and during our tests, we experienced quick and efficient operation. The output graphs are parametrizable, and people will be able to select the parameters for the variation or fit a better curve.

Needless to say that using this app will require at leas some basic math knowledge in terms of polynomial fits and trigonometric functions. However, having said that, the application does sport an accessible and helpful workflow, enabling less experienced users to reach their results in a more-or-less simple manner. Speaking of basic, for those who are interested in a more minimalist version of the app, the "Basic" version will provide most of the functionality of the "Demo" version, save for some features.

Those who are looking for a program that will help them plot linear regressions and analyze the results can have a look at this application. Its set of tools and predefined function library, combined with the analysis reports it can produce make it a suitable candidate as a regression fitting software.
