ndCurveMaster is a Windows application designed to help you discover optimum equations necessary for describing empirical data via the multiple linear regression method. It can read variables and constants from CSV tables in order to generate the equations and associated graphs.

Find optimum equations to describe empirical data

Following a speedy setup operation that shouldn't give you any trouble, you're welcomed by a simplistic interface where you can get started by opening a CSV file with variables (x, y) and constants. There are two types of CSVs supported: USA/UK format (decimal separator is a full stop, value separator is a comma) and EU format (decimal separator is a comma, value separator is a semicolon).

If the CSV information is correctly identified by the application, then you will be able to select the X variables and Y variable from the list while keeping in mind that ndCurveMaster adds all combinations of the X variables. Plus, you can adjust the significance level (alpha).

Sort equations, save history, and view graphs

The software tool then immediately optimizes the equations, which can be sorted in the main window by ID, r-squared or standard error. It is capable of automatically fitting an unlimited number of input variables and it makes use of heuristics for curve fitting.

There are 120 arrays of non-linear equations built into the program. Graphs can be plotted with the click of a button. Moreover, the output equations can be saved to CSV files for closer inspection and safekeeping.

Failed to read multiple x variables

The application carried out tasks rapidly while remaining light on system resources consumption. However, it failed to read CSV files with more than one x variable in our tests ("Too many variables" error message).

All aspects considered, ndCurveMaster offers a straightforward solution for finding optimum equations to describe empirical data using the multiple linear regression method.
