Examples

  • This is the graph of our piecewise defined function.

  • A piecewise function can be easier to analyze because it is broken down into simpler sections.

  • OK, so this would be a piecewise defined function.

  • OK, so now let's go ahead and write them as a piecewise function with their restrictions.

  • You have set of piecewise linear functions.

  • Therefore, the current study reports findings of a piecewise model with equal error variance over time.

  • The piecewise linear variables are continuous between 0 and 1.

  • Piecewise constant transition intensity models allow quite a high degree of flexibility.

  • Finally, modeling the impact of the passage of time in terms of a piecewise linear specification provides for a continuous as well as flexible price index function.

  • We turned instead to a piecewise-linear specification that is described fully in Bryan and Colwell (1982).

Morphology

piecewise = piece (transparent) = piece + wise

Meaning is directly formed from 'piece' + the productive suffix '-wise' meaning 'in the manner of' or 'by piece', yielding 'in separate parts'.

Etymology

Piecewise comes from piece ('a part') and the ending -wise ('in the way of'), the same -wise you see in clockwise. So it means 'in parts' or 'by pieces', which is why a piecewise function or model is made from different rules for different parts.
