Non-linearity

Similar term(s): non-linear change.

A non-linear change is a change that is not based on a simple proportional relationship between cause and effect. Therefore, such changes are often abrupt, unexpected, and difficult to predict.

Source: GreenFacts

A relationship or process in which a small change in the value of a driver (i.e., an independent variable) produces a disproportionate change in the outcome (i.e., the dependent variable).

Relationships where there is a sudden discontinuity or change in rate are sometimes referred to as abrupt and often form the basis of thresholds. In loose terms, they may lead to unexpected outcomes or “surprises”.
