Etymology: From French paramètre, from New Latin parametrum (“parameter”), from Ancient Greek παρα- (para-, “beside”) + μέτρον (métron, “measure”).
Senses: examples: text: As molecular surface-to-surface contacts control both solution phenomena and surface phenomena, it is not surprising that various correlations of cohesion parameters and surface phenomena can be found.

text: The independent parameters of a system or network over F(z) reflect its structure and determine its structural properties (such as the reducibility of coefficient matrix A and its characteristic polynomial det(λI −A), controllability and observability over F(z), etc.).

text: On the other hand, if we have suitable data, we may be able to develop some direct computational methods for the essentially nonlinear parameter identification problems, in which fewer or even no nonlinear processes are involved.
