Spline regression (a.k.a. piecewise polynomials or segmented regression)

Troubleshooting


Problem

How can I test a regression model where I expect the slope to shift up or down, or even change sign, at a particular value of the predictor? What if I expect all values of the response variable to be increased by some constant if the predictor exceeds a certain value?
