Least Squares Regression Predictor

Dynamically adjust a line of best fit to actively minimize the sum of squared residuals (SSE) compared to the true OLS regression model.

Margin of Error Simulator

Visualize exactly what the Margin of Error means geometrically. Observe how increasing sample size shrinks it while demanding higher confidence widens it.
