Who is right  Abraham Weishaus or Coaching Actuaries?
ASM claims that the joint life failure probability in markov chain format is t q xy = t p xy (01) + t p xy (02) + t p xy (03)
CA claims it is t q xy = t p xy (01) + t p xy (02) I think Weishaus is correct, but I would like an official statement from both Weishaus and CA. I would also like an apology from CA, since I spent so much time the past 2 days trying to reason this out and getting frustrated when I couldn't figure it out. I got a huge headache yesterday night and couldn't come into work today because of that. I am very upset. This is the 7th error I've caught in your study material.

You may find it amusing, but I don't.
I'm fine with struggling with a concept and spending a few days trying to wrap my head around something, but struggling with a concept because you were provided the wrong information is just infuriating. I just wasted 2 study days trying to internalize this formula, but it just wasn't clicking, so I asked my friend to see what ASM has to say about it. I'm considering changing study materials...

Exiting to states 1 or 2 represent the probability of just 1 dying and the other surviving, but it doesn't account for the case where they both die (Which would still count as a failure). The fact that no one caught this is proof actuarial students just memorize and don't understand what they're doing. This gives credence to my post a couple days ago when I said the latterhalf of this material is bullshit and madeup nonsense.

Are you able to prove Kolmogorov's forward equation without googling it? I doubt many people who passed MLC or will pass LTAM knows how. What about Thiele's Differential Equation? Last edited by Liar; 08172018 at 09:43 PM..
