Parametreid

Parametreid is the Estonian plural noun used to refer to multiple parameters. The term appears across mathematics, statistics, science, and computer science.

In mathematics and statistics, a parameter is a quantity that defines a system or model and is typically not a variable observed directly. It characterizes distributions, models, or processes. Examples include the mean and variance of a distribution, or the coefficients in a regression model.

In computing, parameters specify inputs to functions, procedures, or interfaces. They may be passed to procedures as positional or named parameters, and values can be supplied by the caller as arguments. Parameter passing can be by value or by reference; in application programming interfaces (APIs), parameters appear as query strings or in the request body.

In data analysis and machine learning, model parameters are quantities to be estimated from data. Some models also include hyperparameters, which are set before training. Parameter estimation uses methods such as maximum likelihood, least squares, or Bayesian inference.

Etymology and usage: parametreid is the standard Estonian plural form used in technical writing to refer to multiple parameters. The word appears in equations, code, and documentation, often as a generic placeholder for inputs or characteristics.
