v0.2.3

• Support for weight validity checking when resampling with pf_resample! or pf_resize! with the check keyword.
• By default, a warning will be raised when weights are NaN, or all go to zero (-Inf log weights).

Full Changelog: v0.2.2...v0.2.3

v0.2.2

• Several new particle filter resizing operations, including:
  • pf_introduce! for introducing new particles to a particle filter, optionally sampled from a proposal distribution
  • pf_coalesce! for combining choicemap-equivalent or identical particles into a single particle
  • pf_optimal_resize! for the optimal resizing algorithm of Fearnhead and Clifford (2003)

Full Changelog: v0.2.1...v0.2.2

v0.2.1

Bug Fixes

• Fixed stratified sampling when number of particles is not an integer multiple of the number of strata
• Added missing weight adjustment when performing stratified sampling (#6)

Full Changelog: v0.2.0...v0.2.1
