Limbola likanisi ya variable latente.
Variable latente, eyebani pe na kombo ya variable cachée, ezali variable oyo emonanaka directement te to emesami te, kasi ezuami to e estimé na ba variables misusu oyo ekoki komonana oyo emekamaka directement to e observer. Mbala mingi, ba variables oyo esalelamaka pona ko représenter ba concepts to ba constructions oyo ekoki ko mesurer to ko quantifier na pete te, lokola intelligence, motivation, to satisfaction. Ba variables latentes esalelamaka mingi na ba modèles statistiques, lokola analyse factorielle pe modélisation ya équation structurelle, pona kosunga kolimbola ba relation pe ba corrélations entre ba variables observées ebele. Na ba modèles oyo, ba variables latentes esalaka lokola ba facteurs sous-jacentes oyo e influencer to esalaka ba variables observées, oyo ekoki kosalisa balukiluki ba comprendre structure sous-jacente pe ba causes ya ba données na bango. Ndakisa, na boyekoli ya bosepeli na mosala, balukiluki bakoki komeka ba variables lokola lifuti, esika ya mosala, mpe boyokani ya basali, kasi likanisi ya bosepeli na mosala yango moko ekoki komekama mbala moko te to kotalama te. Na esika na yango, ekoki kozala inférer to estimé lokola variable latente, na kotalaka ba relation pe ba corrélations entre ba variables observées. Na mobimba, bosaleli ya ba variables latentes epesaka nzela na balukiluki koyekola boyokani mpe makambo ya mindondo oyo ekoki komekama to kotalama mbala moko te, kasi ekoki kozwama na nzela ya ba données oyo basangisaka.
