ndCurveMaster - Multivariable Curve Fitting & Data Analysis Software

ndCurveMaster is a unique curve fitting tool that automatically fits multivariable nonlinear regression equations to your datasets using an unlimited number of input variables. For instance, a generated model may appear as follows:

Y = a₀ + a₁·x₁^-5 + a₂·sin(x₂)^-1.3 + a₃·1/4^x₃ + a₄·x₄^-0.2 + a₅·ln(x₅)² + a₆·exp(x₆)² + a₇·cos(x₂)^1/2·ln(x₃)·x₆^-1/3

Whether you are a researcher, engineer, or student, ndCurveMaster offers powerful data analysis capabilities, enabling you to uncover hidden insights and develop accurate predictive models.

Key Features:

• Robust Model Generation: Automatically discover optimal multivariable nonlinear regression equations that describe your data.
• Multivariable Curve Fitting: Analyze data with any number of independent variables.
• Automated Data Analysis: Identify key relationships between variables for deeper insights.
• Comprehensive Fit Evaluation: Benefit from features such as ANOVA, regression diagnostics, multicollinearity checks, residual normality tests, overfitting detection, cross-validation, and variable sensitivity analysis.
