|Discrete Amount Projections are about projecting single or multiple values, or payments, in a timebase. In contrast to projections about rates (eg Constant Rate, Stepped Rate), Discrete Amounts are more like one-off lumps that occur at specific times. There are three families of functions within the Discrete Amount Projections category:|
- The Payments family has functions for inserting one or more payments in a projection. These range from the simple MkPmts to many more advance variations, such as those that grow the payments according to a forecast (MkPmtsGrow, MkPmtsFcst), those that introduce a time delay (MkPmtsLag, MkPmtsLagProf) and those that take out a payment from one part of the projection and put it in another (RePhasePmt, RePhasePmts).
- The Payments Periodic family has functions like the Payments family but that repeat periodically after set time intervals. For example there is MkPmtsPer, which takes a ØPmtIntervalØ in months, and MkPmtsGrow, which does the same thing but grows the payment every time it is applied.
- The Payments Market family uses growth and forecasts like the Payments family, but in a more subtle way. It uses a value from a forecast if no value has been specified against a particular date. So MkPmtsFcstMkt will simply apply it"s Pmts against the PmtDates unless a payment is missing or zero, in which case it will substitute in its place a value from the forecast.
