Description: A novel framework to correct for batch effects prior to
        any downstream analysis in microbiome data based on Projection
        to Latent Structures Discriminant Analysis. The main method is
        named “PLSDA-batch”. It first estimates treatment and batch
        variation with latent components, then subtracts
        batch-associated components from the data whilst preserving
        biological variation of interest. PLSDA-batch is highly
        suitable for microbiome data as it is non-parametric,
        multivariate and allows for ordination and data visualisation.
        Combined with centered log-ratio transformation for addressing
        uneven library sizes and compositional structure, PLSDA-batch
        addresses all characteristics of microbiome data that existing
        correction methods have ignored so far. Two other variants are
        proposed for 1/ unbalanced batch x treatment designs that are
        commonly encountered in studies with small sample sizes, and
        for 2/ selection of discriminative variables amongst treatment
        groups to avoid overfitting in classification problems. These
        two variants have widened the scope of applicability of
        PLSDA-batch to different data settings.
