LineFit Analysis 2.1

LineFit Analysis is a streamlined tool for fitting lines and curves to your data, turning raw measurements into clear, defensible insights. Built for scientists, engineers, and data analysts, it helps you quantify trends, build calibration models, and validate results with transparent diagnostics—without writing code.

Key features:

• Linear and non-linear regression (polynomial, exponential, logarithmic, power)
• Weighted and robust fitting options for noisy or heteroscedastic data
• Goodness-of-fit metrics (R², adjusted R², RMSE) and residual diagnostics
• Confidence and prediction intervals
• Outlier handling and influence indicators
• Interactive plots with annotations and curve overlays
• Calibration workflows, including inverse predictions
• Import from common tabular formats (e.g., CSV); export results and publication-ready charts
• Templates to standardize analyses and enable batch processing
• One-click, shareable reports for audit and collaboration

Ideal for calibration curves, trend analysis, quality control, and research workflows where accuracy, repeatability, and clear communication of results matter.
