Nonlinear regression is a form of regression analysis in which data fit to a model is expressed as a mathematical function.

Discover how linear regression works, from simple to multiple linear regression, with step-by-step examples, graphs and real-world applications.

An algorithm is presented for nonlinear least squares estimation in which the parameters to be estimated can be regarded as all nonlinear (the traditional approach) or reclassified as linear-nonlinear ...

A theoretical framework to study linear and nonlinear Richtmyer–Meshkov instability (RMI) is presented. This instability typically develops when an incident shock crosses a corrugated material ...

A linear relationship (or linear association) is a statistical term used to describe the directly proportional relationship between a variable and a constant.

Linear narratives are the most common form. Sometimes, however, a film might work better with a non-linear plot which presents some or all of the events in a non-chronological order.

Examples Frequent-flier miles are one example of a non-linear change. American Airlines introduced them as a new concept in the 1980s and gained an advantage over its competitors.
