Impacts: - KWLearningProblem::ComputeStats - lancement de l'apprentissage meme si une seule valeur - pas de warninbg, car deja emis lors de la preparation - KWDRNBRegressor::ComputeCumulativeTargetValues, ComputeCumulativeSquareTargetValues - pas de lissage dans le cas particulier d'un seule valeur (effet de bord) - cela permet de predire la valeur unique exacte Tests: - LearningTest\TestKhiops\SideEffects\MonoClass: classification - LearningTest\TestKhiops\SideEffects\MonoValueR: regression
