Linear Model Foundation

Understanding the linear equation that forms the backbone of logistic regression

Logistic regression builds upon linear models. Before we transform outputs to probabilities, let's understand how linear models work with continuous data and see their unlimited output range.

The equation y = mx + b forms the foundation. Try dragging on the plot to adjust the line and see how it fits the data.

Data Points:50
Output Range:(-∞, +∞)

Understanding Linear Models

  • Linear models predict continuous values anywhere from -∞ to +∞
  • Slope (m) determines how much y changes per unit of x
  • Intercept (b) shifts the entire line up or down
  • For classification, we need bounded outputs (probabilities)

Interactive Tips

  • • Click and drag on the plot to adjust the line
  • • Switch between slope and intercept modes
  • • Enable residuals to see prediction errors
  • • Try the demo animation to see optimal fitting
