Nettet19. jan. 2024 · Nonlinearity is a statistical term that describes the relationship between dependent and independent variables. It describes a link that cannot be expressed with a straight line. If a system does not follow the linearity theorem, it is referred to as nonlinear. A linear relationship is, therefore, one that can be expressed using a straight line. NettetVideo Transcript.
