J'utilise un modèle non récursif avec Lavaan. Cependant, il s'est passé deux choses que je n'ai pas bien comprises. Premièrement, les indices de la marge de conformité et certaines erreurs types étaient «NA». Deuxièmement, les deux coefficients entre deux variables de directions différentes n'étaient pas cohérents (partie non récursive: ResidentialMobility - Author): l'un était positif et l'autre était négatif (au moins, ils devraient être dans le même sens, sinon, comment Explique?). Est-ce que quelqu'un peut m'aider? S'il vous plaît laissez-moi savoir si vous voulez que je clarifie plus. Merci!Indices de qualité d'ajustement "NA"
