|Instantaneous Level Projections are quite different from the projections about rates and amounts that other preceding projections categories like Stepped Rate Projections deal with. Whereas the other categories generally deal with flows of money, or production, rent, whatever, Instantaneous Level Projections are about looking up a level according to the prevailing date. They are more like a lookup. |
There are 5 families in this category:
- Levels is similar to the Stepped Rate From and Stepped Rate To families, except that what is returned is a level at a particular time, not the results of applying a rate over a time period. So the familiar models of functions are present such as Level (whose constant rate equivalent would be Con), FLevels (stepped rate equivalent FStep) etc.
- Levels Market, is the levels equivalent of the Stepped Rate Market family, with functions such as FLevelsGrowMkt and TLevelsFcstMkt. As usual with the ...Mkt... feature, the function uses specified levels where they are non-blank and non-zero, otherwise it defaults to a level read off a forecast.
- Growth is about the various ways of applying GrowthRates to inflate a figure in the future. Grow simply applies GrowthRates and GrowthDates to inflate a figure from one date to another, with the added ability to specify, via RevMonthsOpt, whether that growth is applied continuously or in steps, every few months. FGrowStep and TGrowStep allow you to specify the dates of those steps (using FromDates or ToDates), and there a further group of functions that use the ...Mkt... feature to either use a specified level or one off a supplied forecast.
- Forecast is a very basic family concerned with looking up values off a forecast. Fcst is simple, popular and versatile and does just this kind of lookup.
- Forecast Specific Times is about when the supplied forecast is not regularly time-spaced as is the requirement in the Forecast family and forecasts generally. The basic workhorses are FcstT and TFcstT, which use FcstFromDates and FcstToDates respectively to allow specification of the forecast.
