Announcing the new nimbleMacros package on CRAN, which provides more compact ways to specify linear model components or other model components in the nimble hierarchical modeling language. You can also write your own model macros.

New versions of nimble and nimbleHMC are available on CRAN. nimble now includes a Barker block sampler for MCMC, better implementations of Laplace approximation and adaptive Gauss-Hermite quadrature, and calling any user-provided optimization function.

RT @MaelisKervellec: 🚨 The second article of my PhD is out 🥳 We integrated commute-time distance⚡ into dynamic occupancy models using @R_ni….

We've updated nimbleEcology to use nimble's automatic differentiation features, allowing its occupancy, capture-recapture, HMM, and N-mixture models to work with HMC, Laplace approximation, and other AD algorithms. @Ben_R_Goldstein.

Minor update to nimbleHMC, with No-U-turn Hamiltonian Monte Carlo samplers for nimble models: Version 0.2.2 includes better diagnostic checking for AD (automatic differentiation) support in any parts of a model to be sampled by HMC.

nimble 1.2.0 is out! (details: . Includes adaptive Gauss-Hermite quadrature, better Laplace approx, Pólya-gamma sampler, noncentered sampler, revamped MCEM, new ways to provide your own distributions and functions with internal data, and some speedups.

We've released an updated version of Hamiltonian Monte Carlo (our implementation of the NUTS sampler) for nimble in package nimbleHMC (. Among other things, it fixes an efficiency glitch in the initial release.

If you're at #JSM2023 and interested in hearing the latest about nimble for MCMC and beyond, I'll be talking about Hamiltonian Monte Carlo (NUTS) and Laplace approximation using nimble's new automatic differentiation features. Wed 9:05-9:20 CC-206B.
