Hi Derek,
I think I have been able to construct a model which works. i found a couple of earlier conversations around using the order parameter and have followed those conclusions to get the following (see below for code). I think I have done this right so that the model isnt assuming that one phase is earlier than the other, right? its just that the results seem a bit too good to be true!
I think that the order command has also worked. My only problem is I dont know how to read the results. I click on the little raw data icon which brings up the probability table but Im afraid my very limited stats knowledge is being stretched beyond capacity. im sure its a dumb question but how do I convert this to the "There is a XX% probability Y burials began before Z burials", you mentioned above?
Thanks again
Chris
