Piecewise Linear Regression. Suppose that y is piecewise linearly related to x . That is, different linear relationships are appropriate over the intervals -∞<x ≤x^* and x^*<x<∞(a) Show how indicator variables can be used to fit such a piecewise linear regression model, assuming that the point x is known. (b) Suppose that at the point x^* a discontinuity occurs in the regression function. Show how indicator variables can be used to incorporate the discontinuity into the model. (c) Suppose that t

In Example 7.3 we showed how a linear regres- sion model with change in slope at some point (xmin < ( Xmax) could be fitted using splines Develop a formulation of the piecewise linear regression model using indicator variables Assume that the function is continuous at point

SOLVED:Continuation of Problem 8.7 . Show how indicator variables can be used to develop a piecewise linear regression model with a discontinuity at the join point t
