Nimble made reddit9/15/2023 ![]() ![]() December 13, 2022: We’ve released Version 0.13.1 This version exists solely to address some developer-level issues required by CRAN and is identical to version 0.13.2 from a user perspective. ![]() We’ve released the newest version of NIMBLE on CRAN. Please see the NEWS file in the source package or the nimble-dev GitHub site for more detailed information. Enhancing error trapping and warning messages.Improving the WAIC system in a few small ways.Improving control of the `addSampler` method for MCMC.Fixing a bug in conjugacy checking causing incorrect identification of conjugate relationships in models with unusual uses of subsets, supersets, and slices of multivariate normal nodes.Fixing a bug (previously reported in a nimble-users message) giving incorrect results in NIMBLE’s cross-validation function (`runCrossValidate`) for all but the ‘predictive’ loss function for NIMBLE versions 0.10.0 – 0.13.2.In addition to the new functionality above, other enhancements and bug fixes include: The best place to reach out for support is still the nimble-users list. In particular, given these major additions to the NIMBLE system, we anticipate the possibility of minor glitches. We’re excited for users to try out the new features and let us know of their experiences. These are documented via the R help system and a new section at the end of our User Manual. A parameter transformation system allowing algorithms to work in unconstrained parameter spaces when model parameters have constrained domains.Support in NIMBLE’s algorithm programming system to obtain derivatives of functions and arbitrary calculations within models.A Hamiltonian Monte Carlo (HMC) MCMC sampler implementing the NUTS algorithm (available in the `nimbleHMC` package).A Laplace approximation algorithm that allows one to find the MLE for model parameters based on approximating the marginal likelihood in models with continuous random effects/latent process values.This version provides substantial new functionality. We’re very pleased to announce the release of version 1.0.0 of NIMBLE. ![]()
