RobustFit.Core

A lightweight .NET library for robust regression analysis, designed to provide reliable estimates in the presence of outliers and anomalies in datasets.

NuGet License: MIT

Features

  • OLS Regression: Standard ordinary least squares implementation
  • Robust Regression: IRLS (Iteratively Reweighted Least Squares) implementation
  • Multiple Loss Functions:
    • Huber loss - balanced approach with tunable sensitivity to outliers
    • Tukey (bisquare) loss - complete outlier resistance for extreme cases
    • Custom loss function support via ILossFunction interface
  • Simple API: Consistent interfaces for all models
  • Comprehensive Linear Algebra: Matrix operations, residuals calculation, and more
  • Performance Optimized: Efficient implementation for .NET applications

Installation

Install-Package RobustFit.Core

Or with .NET CLI:

dotnet add package RobustFit.Core

Quick Start

Ordinary Least Squares (OLS)

using RobustFit.Core.Models;

// Create and fit OLS model
var ols = new OLSRegressor();
ols.Fit(X, y);

// Make predictions
double prediction = ols.Predict(newDataPoint);

Robust Regression with Huber Loss

using RobustFit.Core.Models;
using RobustFit.Core.LossFunctions;

// Create loss function with tuning parameter
var huberLoss = new HuberLoss(c: 1.345);

// Create and fit robust model
var robust = new RobustRegressor();
robust.Fit(X, y, huberLoss, maxIter: 100, tol: 1e-6);

// Make predictions
double robustPrediction = robust.Predict(newDataPoint);

Documentation and Source Code

  • Full documentation and examples: GitHub Wiki
  • Source code: GitHub Repository
  • Sample application: See the demo project in the GitHub repository

When to Use

  • When your dataset contains outliers or anomalies
  • When you need regression models that are resistant to extreme values
  • When standard OLS regression produces poor results due to influential points
