%description
A system for writing hierarchical statistical models largely compatible
with 'BUGS' and 'JAGS', writing nimbleFunctions to operate models and do
basic R-style math, and compiling both models and nimbleFunctions via
custom-generated C++. 'NIMBLE' includes default methods for MCMC, Laplace
Approximation, Monte Carlo Expectation Maximization, and some other tools.
The nimbleFunction system makes it easy to do things like implement new
MCMC samplers from R, customize the assignment of samplers to different
parts of a model from R, and compile the new samplers automatically via
C++ alongside the samplers 'NIMBLE' provides. 'NIMBLE' extends the
'BUGS'/'JAGS' language by making it extensible: New distributions and
functions can be added, including as calls to external compiled code.
Although most people think of MCMC as the main goal of the 'BUGS'/'JAGS'
language for writing models, one can use 'NIMBLE' for writing arbitrary
other kinds of model-generic algorithms as well. A full User Manual is
available at <https://r-nimble.org>.
