In mathematics, extrapolation is the process of estimating, beyond the original observation range, the value of a variable on the basis of its relationship with another variable. It is similar to interpolation, which produces estimates between known observations, but extrapolation is subject to greater uncertainty and a higher risk of producing me...

(ek-strap″o-la´shәn) inference of one or more unknown values on the basis of that which is known or has been observed; usually applied to estimation beyond the upper and lower ranges of observed data as opposed to interpolation between data points.

Extrapolation is when the value of a variable is estimated at times which have not yet been observed. This estimate may be reasonably reliable for short times into the future, but for longer times, the estimate is liable to become less accurate.

The estimation or determination of what will happen in the future by extending (extrapolating) known information or data. The verb usage 'extrapolate' is common and means using mathematics or other logical process to extend a proven trend or set of data. 'What if?..' scenarios and business modelling generally involves some sort of extrapolation. It...

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.
