This page details the version history of the development version of multistate, hosted on this website, which can be installed by typing in Stata,

or updated by typing adoupdate multistate.

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
