Thanks EulerFan101!
Also, can anyone please explain the difference between a vertex and an apex? Thanks!
I am so sorry RazzMeTazz - I wrote up a post earlier, but for whatever reason it's gone!! Thankfully, I kept the image, see attached. (edit: Apparently it's too large, grrrr. Explains why it didn't post last time, though... If you still want it, PM me an e-mail, I'll send it that way. Otherwise, see statement
Basically, I disagree with the way it's worded - it makes no sense, and following it their answers seem to make no sense (note: I did initially read it wrong and went straight north instead of west, but it basically means my triangle is rotated 90 degrees clockwise from what it should be - all values would be exactly the same)
I have a transition matrix diagram question:
In a transition matrix diagram do you have to label a loop around a point, with 100%, if there is no transition away from that point? E.g A proportion of 1 of the people at A will be at A after the next transition...
If you do not label the 100% loop on the diagram is it still technically correct or not? Because to me it seems redundant however I can also see why it should be there.
Yes, you should. If A doesn't point to itself, and doesn't point to anything else, then the interpretation is that we can't continue on from A. However, this makes no sense, since the idea of a transition matrix is that it can be applied an infinite amount of times. So, A should always continue on to something, even if this means you must point it to itself.
Alternatively, if you have no loop, someone else reading your information would just assume you've forgotten about it, and would have no idea where A actually goes, and might just make a guess which completely ruins your data.
(note: I don't know how strict VCAA are on this - I'm speaking strictly from a statistician's point of view)
