Linear regression with a structural break. In econometrics and statistics, a structural break is an unexpected change over time in the parameters of regression models, which can lead to huge forecasting errors and unreliability of the model in general.
Segmented linear regression with two segments separated by a breakpoint can be useful to quantify an abrupt change of the response function (Yr) of a varying influential factor (x). The breakpoint can be interpreted as a critical , safe , or threshold value beyond or below which (un)desired effects occur.

His aim was to generalize the data using as few planes as possible and maintain a constant “blanket of error”.
