{{Short description|Variable that is not directly observed but is rather inferred (through a mathematical model) from other variables that are observed (directly measured)}}
In [[statistics]], '''latent variables''' (from [[Latin]]: [[present participle]] of ''lateo'' (“lie hidden”), opposed to [[observable variable]]s) are [[Variable (mathematics)|variables]] that are not directly observed but are rather [[Statistical inference|inferred]] through a [[mathematical model]] from other variables that are observed (directly measured). Mathematical models that aim to explain observed variables in terms of latent variables are called [[latent variable model]]s. Latent variable models are used in many disciplines, including [[psychology]], [[demography]], [[economics]], [[engineering]], [[medicine]], [[physics]], [[machine learning]]/[[artificial intelligence]], [[bioinformatics]], [[chemometrics]], [[natural language processing]], [[econometrics]], [[management]] and the [[social sciences]].
