Polynomial Regression

Discover the patterns that a straight line cannot capture. Polynomial Regression is a focused, interactive learning and analysis tool for fitting polynomial curves to your own data. Enter x and y values, choose a degree from 1 to 5, and instantly explore the fitted curve and key goodness-of-fit statistics. Whether you are a student learning regression, a teacher demonstrating curve fitting, or anyone exploring nonlinear trends, the app turns polynomial regression into a clear visual experience. Key features: - Fit polynomial models from degree 1 to 5 - Enter and edit up to 30 x-y data points - View the fitted curve, observations, and residuals - Compare R-squared, adjusted R-squared, and RMSE - Inspect fitted coefficients - Learn underfitting and overfitting in plain language - Simulate data by changing degree, curvature, noise, and sample size - Load practical example datasets with one tap - Read beautifully rendered formulas without an internet connection - Keep your latest data and degree selection between sessions Built for focused exploration: - Fully offline math and formula rendering - No account or sign-in required - Lightweight, responsive interface - Clear explanations designed for learners From a simple line to a flexible cubic curve, Polynomial Regression helps you see how model degree changes the fit - and why the best-looking curve is not always the best model. Download Polynomial Regression and turn your data into a curve you can understand.
