%description
The SALTSampler package facilitates Monte Carlo Markov Chain (MCMC)
sampling of random variables on a simplex. A Self-Adjusting Logit
Transform (SALT) proposal is used so that sampling is still efficient even
in difficult cases, such as those in high dimensions or with parameters
that differ by orders of magnitude. Special care is also taken to maintain
accuracy even when some coordinates approach 0 or 1 numerically.
Diagnostic and graphic functions are included in the package, enabling
easy assessment of the convergence and mixing of the chain within the
constrained space.
