Web27. There is a pervasive mistake in your post, possibly explaining your trouble, which is to believe that ( X t) t ⩾ 0 being a Markov process means that E ( X t ∣ F t − 1) = E ( X t ∣ X t − 1) for every t ⩾ 1, where F t = σ ( X s; 0 ⩽ s ⩽ t) for every t ⩾ 0. This is not the definition of the Markov property. WebExplained Visually.
