36. Dynamic Cohort Models

You may want to create Markov models with a specified cohort size, perhaps for budget analysis. This chapter describes how to create models where the cohort is larger than one and/or models where the cohort size is being changes with time. This chapter also covers reporting options for such models.

Note that Dynamic Cohort models can be run as Expected Value calculation models or via Microsimulation, depending on your project needs.

 

The techniques described in this section related to dynamic cohort size is often applicable in Budget Impact Models (TreeAge generates outputs needed for Budget Impact Analysis). By beginning with a population of a determinate initial size and adding to the cohort to reflect incidence, your model will generate a much clearer picture of the overall cost to a payer over time.
