Instead of directly modeling their behavior, researchers use trial and error to come up with plausible values for key parameters—the rate at which clouds over the ocean turn to rain, say.

When parameter is used to mean "a boundary or limit," it is usually in its plural form, and often as the object of a preposition such as within or beyond: Let's face it, managing weight loss or maintenance …

When a system is modeled by equations, the values that describe the system are called parameters. For example, in mechanics, the masses, the dimensions and shapes (for solid bodies), the densities and …

parameter, in mathematics, a variable for which the range of possible values identifies a collection of distinct cases in a problem. Any equation expressed in terms of parameters is a parametric equation.

Parameters are factors or limits which affect the way that something can be done or made. That would make sure we fell within the parameters of our loan agreement.

For example, a budget can be thought of as a set of parameters that determine a range of activity, much like a set of mathematical parameters that establish the range of effects, or limits, of other variables.

Learn what parameters are, how they shape analytics and AI models, and why adjusting parameters is critical to accuracy, performance, and reliable decision-making.
