Breakpoint regression analysis
WebEstimation and inference of regression models with piecewise linear relationships, also known as segmented regression models, having a fixed number of break-points. … WebThe use of piecewise regression analysis implicitly recognizes different functions fit to bedload data over varying ranges of flow. The transition from primarily low rates of sand transport (Phase I) to higher rates of sand and coarse gravel transport (Phase II) is termed "breakpoint" and is defined as the flow where the fitted functions intersect.
