koppelingcoëfficiënt
A koppelingcoëfficiënt, often translated as coupling coefficient, is a dimensionless quantity that describes the degree of interaction or correlation between two or more variables, systems, or phenomena. It quantifies how changes in one entity are associated with changes in another. In statistical contexts, it is closely related to measures of correlation, such as Pearson's correlation coefficient, which ranges from -1 to +1. A value of +1 indicates a perfect positive association, where an increase in one variable corresponds to a proportional increase in the other. A value of -1 signifies a perfect negative association, where an increase in one variable corresponds to a proportional decrease in the other. A value of 0 suggests no linear association between the variables.
Beyond statistics, the concept of a koppelingcoëfficiënt appears in various scientific and engineering fields. In physics,
