As least-squares linear error does not depend on whether the chord whose error is being measured is 1:''r''<sub>1</sub>:''r''<sub>2</sub>:...:''r''<sub>''n''</sub> or the same chord linearly shifted to have root α, it can be used as a distance function between two delta signatures with no free terms. | |||
