Uniformise notation

[maxbiostat]

Good gawd, we need to uniformise the notation in the manuscript!

I personally strong dislike the p(theta | y) ~~ p(y | theta)p(theta) notation because it overloads the letter p with wildly different things. In my writing I usually use p(theta|y) for the posterior, Pr(A|y) for the probability of an event A conditional on the data, f(y|theta) for the likelihood and \pi(theta) for the prior.

Whatever we choose, we should be consistent with it.

We also need to uniformise other terms, such as the number of iterations/simulations. I usually use M, leaving N for data set sizes.
