THE FINTECH BUILDER · SYNTHETIC LEARNING LAB

GARCH

Separate new shock information from carried variance.

0.08
0.9

Keyboard: Tab to a control; native arrow keys change sliders. Alt + Right steps, Alt + Left goes back. Reduced-motion Play advances one state only.

  1. 1. Read explicit initial variance
  2. 2. Square previous residual
  3. 3. Add intercept and α shock term
  4. 4. Carry β times previous variance
