Linear interpolation - Wikipedia
https://en.wikipedia.org/wiki/Linear_interpolationAccuracy. If a C 0 function is insufficient, for example if the process that has produced the data points is known to be smoother than C 0, it is common to replace linear interpolation with spline interpolation or, in some cases, polynomial interpolation.. Multivariate. Linear interpolation as described here is for data points in one spatial dimension.

www.wallstreetmojo.com › extrapolation-formulaExtrapolation Formula refers to the formula that is used in order to estimate the value of the dependent variable with respect to an independent variable that shall lie in range which is outside of given data set which is certainly known and for calculation of linear exploration using two endpoints (x1, y1) and the (x2, y2) in the linear graph when the value of point which has to be extrapolated is “x”, a formula that can be used is represented as y1+ [ (x−x 1) / (x 2 −x 1 )] * (y 2 ...

Extrapolation - Wikipedia
https://en.wikipedia.org/wiki/ExtrapolationIn mathematics, extrapolation is a type of estimation, beyond the original observation range, of 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 uncertaintyand a higher risk of producing meaningless results. Extrapolation may also mean ext…
