[QUOTE="bootsking, post: 1012053, member: 4596"] From a strict statistical perspective this appears to be a classical application of "over-fitting", meaning there needs to be some reason to use a more complex model (eg spline, etc) to simply make the curve go through all of the data points. What is the technical reason that suggests this extreme complex behavior? In this case the most fundamental rationale is to first determine the velocity variance at a given temperature (we know it is not constant, as evidenced by the usual characterization of the standard deviation), and compare resulting error of the simplest regression to judge whether a more complex model is needed. In other words statistical analysis supports the KISS principle! [/QUOTE]
