Rivu Basu Simulation Lab

Regression as a living experiment.

Build datasets, bend the fit, test predictions, and learn by doing. This upgraded lab turns a single regression demo into a guided simulation studio with missions, challenge mode, live diagnostics, notebook snapshots, and coach-style explanations.

Quick Start

Suggested
1. Build a clean signal

Use the strong linear preset. Fit the model and notice how high R² and low RMSE reinforce each other.

2. Break the pattern

Add an outlier or switch to the curved preset. Compare the fitted model to the draggable comparison line.

3. Explain the result

Capture a snapshot and use the coach text plus your own notes to explain whether the regression is trustworthy.

Rivu Basu Simulation Lab is designed for hands-on statistical intuition: experiment first, quantify second, explain third.
