bayesSSM 0.7.1

• Small documentation fixes.

bayesSSM 0.7.0

• Add auxiliary_filter and resample_move_filter for auxiliary and resample-move particle filters.
  See all supported filters in ?particle_filter.
  
• Refactor pmmh and internals to support multiple particle filters.
  
• Add pf_wrapper argument to pmmh to specify which particle filter to use.
  
• Improve argument checking by switching to the checkmate package, providing clearer and more consistent error messages.
  
• Make minor edits to README and vignettes for clarity.

bayesSSM 0.6.1

• Improved reproducibility of pmmh: Setting a seed now ensures consistent results regardless of the number of cores used.
• Improvement performance of pmmh slightly.
• Rewrote resampling step in particle_filter to C++ for improved performance.
• Added new article detailed-overview which goes over some theory, implementation details, and tips for using the package effectively.
• Improved the documentation of the package, including the README and articles, to provide clearer explanations and examples.

bayesSSM 0.5.0

• The particles argument in init_fn, which is passed to particle_filter and pmmh, is deprecated. Please use num_particles instead. A warning will be issued if particles is used.
• Added support for time dependency in functions. You can now use t in transition_fn and likelihood_fn when passing them to particle_filter and pmmh. This allows for time-varying transition and likelihood functions.
• Fixed a bug in particle_filter in likelihood calculation causing it to be shifted by a constant.
• Improved robustness of pmmh when encountering very low log-likelihood values.
• Added scaling for the proposal covariance when using "logit" in pmmh.
• Improved documentation: updated package description, clarified text in the README and vignette, and added more unit tests.

bayesSSM 0.4.7

• Initial CRAN submission.
