|Interpolated and Curve-Fitted Levels family|
|Projecting Interpolated and Curve-Fitted Levels against future points in time|
|Description: This family is the equivalent, in terms of levels, of the Interpolated and Curve Fitted Rates family, the latter of which could be considered as the integral (area under the curve) of the former.|
|Introduction: This family is for when you have a number of levels at various points in time and you need to be able to project inbetween them, say for a forecast of prices.|
The two ways of projecting using an input range of data points correspond to the two functions in this family:
Which function you use depends on whether you have an exact series of data points that you just want to interpolate between, in which case you want InterpedLevel, or that you have a set of approximate points that you just want to fit a curve to.
Note that if you want to fit a straight line, you can specify a polynomial order of 1 in FittedLevel, (although BF also has its LinReg function, specially for this purpose).
