pomp version 1.9 is now available on CRAN. This release fixes several bugs.
Bug fixes
- During particle filtering, when non-finite
dmeasure
values are generated, an error is generated and the offending parameters, states, data, and time are reported. In methods that use parameter transformations (transform=TRUE
), the reported parameters were on the transformed (estimation) scale, which can be confusing. The error message now gives the parameters on the natural (model) scale. - A bug in
mif2
arising when filtering fails in the final timestep has been fixed. In this case, when all particles are deemed inconsistent with the data, we use an unweighted mean (with a warning) in place of the default weighted mean.
