8.2 Finding all paths

  1. Start at the treatment variable
  2. Follow one of the arrows coming in/out of the treatment variable to find another variable
  3. Follow one of the arrows coming in or out of that variable
  4. Keep repeating step 3 until you either come to a variable you’ve already visited (loop!), or find the outcome variable (path)
  5. Every time you find a path/loop, back up one and try a different arrow in/out until you’ve tried them all. Then, back up again and try all those arrows

Let’s practice!
