ndCurveMaster

ndCurveMaster is the first and only program to find the ideal equation to allows the auto-fitting of an unlimited number of input variables, for example: y= a0 + a1*x1^(-11) + a2*x3 + a3*x5^3 + a4*[ln(x8)]^3 + a5*[exp(x1*x4)]^(-2) + a6*x1*x8^2 + a7*ln(x2*x6) + a8*x3*x4. It was designed to find optimum nonlinear equations to describe empirical data using only a multiple-regression method, and is the first regression program that offers an overfitting detection option.

ndCurveMaster was tested positive for 500,000 cases and 10 variables.

Features

• Auto-fitting of an unlimited number of input variables: x1, x2, x3,..., xn and their combinations: x1*x2, x1*x3, x2*x3,...,x1*x3*x3,..., x(n-2)* x(n-1)*xn
• Detect and prevent overfitting
• Optimized to work with large amounts of data
• Heuristic techniques for data fitting by the use of random iterated or full random search alghorithms
• Full statistical analysis of every equation
• Stepwise regression with backward elimination
• Multicollinearity detection by the use of a Variance inflation factor (VIF)
• Detect and prevent overfitting
• The model with or without an intercept term
• User can freely expand or reduce the model
