%description
Bayesian supervised predictive classifiers, hypothesis testing, and
parametric estimation under Partition Exchangeability are implemented. The
two classifiers presented are the marginal classifier (that assumes test
data is i.i.d.) next to a more computationally costly but accurate
simultaneous classifier (that finds a labelling for the entire test
dataset at once based on simultanous use of all the test data to predict
each label). We also provide the Maximum Likelihood Estimation (MLE) of
the only underlying parameter of the partition exchangeability generative
model as well as hypothesis testing statistics for equality of this
parameter with a single value, alternative, or multiple samples. We
present functions to simulate the sequences from Ewens Sampling Formula as
the realisation of the Poisson-Dirichlet distribution and their respective
probabilities.
