Inconsistency of Pitman-Yor process mixtures for the number of components
Jeffrey W. Miller, Matthew T. Harrison
In many applications, a finite mixture is a natural model, but it can be difficult to choose an appropriate number of components. To circumvent this choice, investigators are incre…
Importance sampling for weighted binary random matrices with specified margins
Matthew T. Harrison, Jeffrey W. Miller
A sequential importance sampling algorithm is developed for the distribution that results when a matrix of independent, but not identically distributed, Bernoulli random variables…
A simple example of Dirichlet process mixture inconsistency for the number of components
Jeffrey W. Miller, Matthew T. Harrison
For data assumed to come from a finite mixture with an unknown number of components, it has become common to use Dirichlet process mixtures (DPMs) not only for density estimation,…
Exact sampling and counting for fixed-margin matrices
Jeffrey W. Miller, Matthew T. Harrison
The uniform distribution on matrices with specified row and column sums is often a natural choice of null model when testing for structure in two-way tables (binary or nonnegative…
