Ages
Simulation output is stored in the Library using Age Types. Age Groups are used for post processing and summarizing output in charts and maps.
Age Types
Age Types specifies the resolution at which summary output for states and transitions can be disaggregated according to age. If no age types are defined, summary output cannot be disaggregated by age in charts or output reports.
If Age types every is set to 1 timestep, summary output will be disaggregated in 1 timestep age bins. Defining age types every 10 timesteps only allows disaggregation in 10 timestep age bins. The smaller the value used, the more space will be used by the library on disk as more records are required for finer resolution age bins. If no value for Age types every is selected (default), then summary output will not be disaggregated by age. This option uses the least space on disk.
Values above the Maximum reporting age will all be lumped into a single bin when disaggregating summary output by age.
Age Groups
Age Groups allows for the creation of a coarser set of bins than is defined in Age Types, and can be modified after a simulation is run, whereas age types cannot. For example, age types can be defined every timestep whereas age group bins can be 20, 55, 73, and so on. Any bin choice will work as long as it is divisible by the age type frequency, e.g., if age types are defined every 10 timesteps, then an age group at 25 would not work. Mismatching age bins and groups will result in a warning when generating charts.
The Maximum age field in the Age Groups table defines the upper boundary of each age group bin. Adding the Color field (accessible from the Context Menu) to the table allows for the customized color mapping of age bins. Double click in a cell to open the color editor and choose a color.
