Hi all, Stupid question I'm sure but could someone please explain this. When we take the lambda and the mu outside of the brackets, the negative 1 is only subtracted away from the MY(t) and not the MX(t) like it was in the line above. Could someone please explain the step in between? Thanks a lot, Tom
They have taken lemda+mu outside. If you see it by again taking (lemda+mu) inside, you will get: exp{[Lemda×Mx(t) + mu×My(t) - Lemda -mu]} Same expression as above. Moreover, see the formula attached below in the pic.
