multistate - Stata version history on SSC

This page details the version history of the stable version of multistate on SSC.

25jul2019: version 2.3.1

  • bug fix: edits in merlin function names (1.2.5) caused predictms to fail; now fixed
  • error check added for bhtime with strcs models - not currently supported

03jun2019: version 2.3.0

  • bug fix: stpm2 and strcs models failed when simulating, introduced in 2.2.0; now fixed
  • streg, dist(lognormal) now allowed with clock-forward models
  • bug fix: streg, dist(lognormal) with reset incorrectly assumed loglogistic; now fixed

28may2019: version 2.2.0

  • bug fix: with novcv() when ci not specified introduced in 2.1.0; now fixed
  • bug in error check for log normal requiring reset; now fixed
  • Generalised gamma streg model now supported when used in the models() syntax
  • bug fix in msaj when number of transitions was not equal to dimension of transmatrix()

15apr2019: version 2.1.0

  • novcv() option added to use mean vector instead of draws in CI calculations, i.e. assumes a particular transition is estimated without uncertainty

19mar2019: version 2.0.1

  • help file improved for msaj

23feb2018: version 2.0.0

  • bug fix: los was incorrectly scaled to 1, introduced in 1.2.0. Now fixed.
  • normal approximation for CIs is now the default. percentile option replaces normal.
  • bug fix: level() was ignored in CI calculations, always assumed 95%. Now fixed.
  • gen() removed
  • bug fix: in some cases mm_root_vec produced an error when solving the root. Now fixed.
  • all predictions now available in one call
  • infinite at#()s added (limited to 50 for error check reasons)
  • at() changed to at1()
  • difference option added
  • added atref(#) - default 1
  • standardise option added to calculate standardised (sample-averaged) predictions
  • bug fix: with Stata 15 and streg (apart from dist(exp)), with at2(), the ancilary parameter constant was ignored. Now fixed.
  • _time = 0 now allowed with normal ci’s
  • userfunction() added for user-defined prediction function, subroutines for probs and los
  • userlink() added for normal cis of userfunction() - default identity, can also be log or logit
  • cr option added to avoid specifying a transition matrix. For use with models() only.
  • bug fix: reset now synced with root-finding updates for stpm2 and strcs models
  • outsample added
  • stms added
  • enter() removed, now min(timevar or _t)
  • aj added for Aalen-Johansen estimator with Markov models
  • reversible transitions now allowed

17nov2017: version 1.2.1

  • bug fix with simulation from strcs models with delayed entry

13nov2017: version 1.2.0

  • tscale2() and time2() added for transition-specific timescales
  • probabilities scaled to 1

21nov2016: verison 1.1.1

  • bug fixes

16nov2016: version 1.1.0

  • some re-writes of source code for massive speed improvements when root-finding required
  • trans#() syntax removed, now parsing is done automatically and using covariates expanded using msset
  • model#() changed to models()
  • improvements to help files
  • covariates() added to msset to create transition-specific dummies, which must be used in model fitting (if required)
  • default n() now 100,000, or 10,000 with ci
  • survival added to calculate all predictions on a standard single event model

09aug2016: version 1.0.1

  • gen() option to allow a stub for created variables, default is pred

12jul2016: version 1.0.0

  • Initial release
