Y-Intercept (b0) vs Slope (b1)

Formel

## Regression Intercept The y-intercept is the predicted value of y when x equals zero. The regression line always passes through the point (x-bar, y-bar). ### Formula **b0 = y-bar - b1 × x-bar** The intercept may not have a meaningful interpretation if x = 0 is outside the range of observed data. The regression equation is: y-hat = b0 + b1 × x.

Lösungsbeispiel

With slope = 0.8333, mean x = 15, mean y = 20.

  1. 01b0 = 20 - 0.8333 × 15
  2. 02b0 = 20 - 12.5 = 7.5005
  3. 03Regression equation: y-hat = 7.50 + 0.833x
