Arithmetic coding is a general technique for coding the outcome of a
stochastic process based on an adaptive model. The expected bit rate is the
cross-entropy rate of the model versus the actual process. PPM, prediction by
partial matching, is an adaptive statistical model of a symbol sequence which
models the likelihood of the next byte based on a (relatively short) suffix of
the sequence of previous bytes.
