The idea of estimating a value by extending information at hand outside its immediate range In LP, an extrapolation estimate of the optimal objective value uses dual price (y) as a slope: z^(b + h) = z(b) + yh For a sequence {x^k}, an extrapolation is an estimate of a limit point
Extrapolation is interpolation extended to points outside the convex hull of a dataset An interpolated value at a point outside the convex hull of an input dataset is referred to as an extrapolated value
an inference about the future (or about some hypothetical situation) based on known facts and observations (mathematics) calculation of the value of a function outside the range of known values
A rigorous process of projecting trends into the future and building confidence intervals around them by adjusting for the effects that known change factors are likely to produce
The prediction of the value of a variable outside the measured range or an inference of the value of a variable of a related outcome (eg the extrapolation of a reduction in the rate of progression to AIDS from a stabilisation or improvement in the CD4 count)
In extrapolation mode, the instrument attempts to track occluded satellites, even after it has lost lock on them, by keeping the channel open and trying to catch the signal again
A scientific method of applying or transferring experimental observations from a model to the real world Extrapolation is frequently necessary because effects in the real world are usually too slow or too minute to measure
