Mutatói

Mutatói is a Hungarian term used in mathematics, statistics and related fields to refer to indicators or indicator-like constructs. The word derives from mutatni, meaning to indicate or show, with a suffix forming a plural or collective sense. In this context mutatói are typically binary signals that signal the presence, membership or activation of a condition.

In mathematics, a common example is the indicator function (also called a characteristic function) of a subset A of a set X. Denoted χ_A, it maps elements of X to {0,1}, with χ_A(x) = 1 if x is in A and χ_A(x) = 0 otherwise. Indicator functions are used to encode sets for algebraic manipulations, integrals and sums, and to express properties succinctly.

In statistics and data analysis, mutatói often refer to indicator variables (dummy variables) that represent categorical data as binary values. These variables are used in regression, classification and other models to incorporate qualitative information, enable interaction effects, and simplify interpretation of results.

Applications span probability, combinatorics, optimization and data science. Indicator-like constructs help convert qualitative statements into quantitative form, facilitate counting arguments, and enable modular modeling of complex systems.
