Watanabe2018_Three state markov model

  public model
Short description
State transition diagram of a three-state Markov model. There are 3 disease states: Healthy, Sick, and Dead, where the Dead state is terminal The yearly transition probabilities are: Healthy to Dead: 0.01; Healthy to Sick: 0.2; Sick to Healthy: 0.1;Sick to Dead: 0.3. Initial conditions: Healthy = 100, Sick = 0 and Dead = 0. Output: Number of people in each state for years 1-10.

  • Disease modelers have been modeling progression of diseases for several decades using such tools as Markov models or microsimulation. However, they need to address a serious challenge; many models they create are not reproducible. Moreover, there is no proper practice that ensures reproducible models, since modelers rely on loose guidelines that change periodically, rather than well-defined machine-readable standards. The Systems Biology Markup Language (SBML) is one such standard that allows exchange of models between different software tools. Recently, the SBML Arrays package has been developed, which extends the standard to allow handling simulation of populations. This paper demonstrates through several abstract examples how microsimulation disease models can be encoded using the SBML Arrays package, enabling reproducible disease modeling.
