  • When plotted, the results of a curvilinear regression often show a curve rather than a straight line.

Examples

  • Unlike linear models, curvilinear regression can account for acceleration or deceleration in relationships between variables.

  • The study employed curvilinear regression to analyze the data.

  • The researchers used curvilinear regression to better model the complex growth patterns in the data.

  • Can you explain how curvilinear regression differs from linear regression?

Morphology

curvilinear + regression

The phrase is a straightforward adjective+noun composition: 'curvilinear' means 'following curves' and 'regression' is a statistical model, so the combined meaning ('a regression that models curved/nonlinear relationships') is directly derivable from the constituents. This follows standard compositional patterns (and has clear equivalents in other languages), so learners who know both words should understand it.

Etymology

Curvilinear regression comes from its parts: curvi- (a 'curve') and linear (a 'line'). It describes fitting a curved shape to data instead of a straight 'line', so the phrase means a regression that uses a 'curve' to show how values change.
