In many practical regression-type problems we cannot fit one uniform regression function to the data, since the functional relationship between the response Y and the regressor X changes at certain points of the domain of X. These points are usually called break points or change points. In such situations, we apply regression models that are obtained by a piecewise definition of the regression function on intervals of the domain of X.
