Generation of nonlinear equations using multiple regression.


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.

  • 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
  • Unlimited multivariate
  • Heuristic techniques for curve fitting:
    • User may repeatedly add new equations to any model from ranking list
    • User can start stepwise regression procedure with backward elimination the least significant variables of any model from ranking list
  • Built-in set includes 120 array of nonlinear equations
  • Powerful and easy to use
  • Full statistical analysis
  • Stepwise regression with backward elimination
  • History and ranking of results
  • Copy or save to CSV file options
  • Any value of significance level alpha
