A sound choice of which extrapolation method to apply relies on a priori knowledge of the process that created the existing data points. Some experts have proposed the use of causal forces in the evaluation of extrapolation methods. Crucial questions are, for example, if the data can be assumed to be continuous, smooth, possibly periodic, etc. Linear extrapolation means creating a tangent line at the end of the known data and extending i… WebMar 27, 2024 · Note that the linear extrapolant uses only the lowest two data points, essentially ignoring the upper data points for this purpose. As such, it implicitly fits a straight line thrugh the points at fs == 5 and 25, then extrapolating that all the way down to 1, .01, .001, .0001. It is as if you had used polyfit on those two data points.
