A parameter specifies a member of a family of mathematical models and is held fixed while a particular solution evolves. Varying it can change equilibrium existence, stability or long-term dynamics, producing a bifurcation. A model parameter differs from its evolving state variables and from an initial condition, even though all may be numerical inputs to a computation.

A parameter is a variable or value that is used in mathematical functions, statistical models, or algorithms to define certain characteristics or behaviors of a system. Parameters help determine the output of a function or model based on their specific values. They can typically be adjusted to influence the results of calculations or simulations. In different contexts, the term "parameter" can have specific meanings: 1. **Mathematics**: In mathematics, a parameter is a constant in equations that can vary within certain limits.
