Welcome to SigmaLab
Your partner for high-quality regression modeling and statistical analysis.
About SigmaLab
SigmaLab is a Poland-based R&D company delivering professional analytics services and scientific software. We help researchers and industry teams turn complex datasets into reliable, defensible results—specializing in multivariable regression, nonlinear modeling, and variance analysis (ANOVA).
ndCurveMaster: Advanced Multidimensional Curve Fitting
ndCurveMaster is our flagship application for n-dimensional nonlinear curve and surface fitting. It accelerates model discovery while preserving scientific rigor—ideal for data-rich projects that demand accuracy, transparency, and reproducibility.
Why ndCurveMaster
- Automated equation discovery: Finds well-fitting functional forms across linear, logarithmic, exponential, power and mixed expressions.
- Multivariable, high-dimension ready: Seamlessly handles many input variables and complex interactions.
- Robust model quality controls: Multicollinearity checks (VIF), overfitting safeguards, cross-validation support, and residual diagnostics (including Q–Q plots and normality tests).
- Speed with traceability: Heuristic search delivers rapid results while keeping a clear, interpretable mathematical form.
- Publication-friendly outputs: Final equations with goodness-of-fit metrics (e.g., R², RMSE) ready for reports and peer-review.
With ndCurveMaster, you gain precise, explainable models—not black boxes—so you can defend decisions, optimize designs, and advance research with confidence.
Consulting & Statistical Services
Beyond software, SigmaLab provides expert analytics to support your project end-to-end:
- ANOVA & experimental design: Factor effects, interactions, and variance decomposition.
- Regression modeling: Linear, nonlinear, and hybrid approaches with transformed predictors.
- Model validation: Assumption checks, residual analysis, multicollinearity diagnostics, and uncertainty quantification.
- Reporting & reproducibility: Clear documentation, clean code/notebooks, and publication-ready figures and tables.
Engage us for rapid feasibility studies, full modeling workflows, or independent review of your existing results.
Who We Help
We work with universities, research institutes, engineering firms, and data-driven businesses that require dependable models and transparent methodology for decision-making, optimization, and scientific publication.
