kahefaktoriline

Kahefaktoriline is an Estonian adjective meaning "two-factor" or "having two factors." It is formed from kahe- (two), faktor (factor), and the adjectival suffix -iline. The term is used across different fields to describe something that depends on or consists of two distinct factors, variables, or inputs.

In statistics and psychology, kahefaktoriline describes models or constructs that can be explained by two latent or observed factors, such as a kahefaktoriline mudel in factor analysis. In information technology, kahefaktoriline autentimine (two-factor authentication) refers to security processes that require two independent credentials, such as a password plus a hardware token or a biometric factor.

Common usage patterns involve applying the term to a framework or method that combines two components into a single structure. The exact factors are defined by the domain, so the noun that follows can vary (for example, mudel, autentimine, or different analytic or security contexts). Grammatically, kahefaktoriline functions as a modifier preceding the noun it describes, aligning with standard Estonian adjective usage.
