Source 
pub fn posterior_predict_multinomial_formula(
    model: &MultinomialSavedModel,
    data: &EncodedDataset,
    n_draws: usize,
    seed: u64,
) -> Result<Array2<u32>, EstimationError>
Expand description

Draw n_draws posterior-predictive replicate class-label assignments for a saved multinomial model on fresh data (#1101). Rebuilds the predict design exactly as predict_multinomial_formula, then samples each row’s class from Categorical(softmax(X·β̂)) (see MultinomialSavedModel::sample_replicate_classes). Returns an (n_draws, N) matrix of class INDICES 0..K aligned to model.class_levels, deterministic in seed.
