| Projecting share variables from history into the simulation time using a saturating projection is a common way to create the business as usual data for these variables. | Projecting share variables from history into the simulation time using a saturating projection is a common way to create the business as usual data for these variables. | ||
| - | There is a subroutine which can be hooked into your model and then called from views which does saturated projections with several parameters. | + | To find the sub-routine related files look in: |
