Piecewise Linear Regression. In Example 7.3 we showed how a linear regression model with a change in slope at some point t ( xmin < t < xmax ) could be fi tted using splines. Develop a formulation of the piecewise linear regression model using indicator variables. Assume that the function is continuous at point t.
