User-visible changes only. For internal changes, see Github commits.
Fix of a bug in the Viterbi algorithm for the calculation of the fitted state at the initial time for each subject.
Bug fix for pmatrix.piecewise.msm
given just intensity matrices instead of a fitted model.
Auto-generated initial values set to a small positive number rather than zero when there are no observed data for a particular permitted transition. This fixes consistency checks (e.g. for qconstraint
) in this situation.
Fix when covariates come into the data as one-column matrices instead of vectors.
Modernised to use roxygen, and pkgdown website created at https://chjackson.github.io/msm
Some internal functions (e.g. deriv.msm
) that clash with base S3 generics renamed
rpexp
is now more efficient. Thanks to Mark Clements. Note that the values simulated by rpexp
, sim.msm
and simmulti.msm
for a specific seed will now be different in models where the intensities are piecewise constant.
Bug fix: in HMMs with partially known initial states specified through obstrue
and censor
, initprobs
is now accounted for.
Bug fix for bootstrapping with character subject IDs.
crudeinits.msm
handled when state is a factor.
Fix for hranges
on multiple parameters.
obstrue
handled in forward-backward algorithm (viterbi.msm
).
