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.
