ndCurveMaster is n-dimensional nonlinear curve & surface fitting program, and:

• Can load a data set consisting of measured values and automatically discovers regression equation set
• Can auto fit an unlimited number of input variables and their combinations
• Utilizes an automated machine learning method for the discovery of equations
• Offers a multicollinearity detection option through the use of a variance inflation factor (VIF) to improve model quality
• Offers an overfitting detection option
• Uses heuristic techniques for curve fitting
• Quickly generates high quality results and saves time

Features:

• Fully automated process curves to fit your data sets
