Description: Provides a robust and sparse method for group-level
        Dynamic Causal Modelling (DCM) of functional magnetic resonance
        imaging (fMRI) data: Student-t weighting of subjects for
        robustness, combined with a nonlocal product-moment (pMOM)
        spike-and-slab prior for sparse selection of group-level
        effects (<doi:10.48550/arXiv.2609.06379>). The package also
        provides an R implementation of single-subject DCM for fMRI
        using variational Laplace inversion (Friston et al., 2003
        <doi:10.1016/S1053-8119(03)00202-7>), including the bilinear
        neural state equation and the Buxton-Friston hemodynamic
        response model, ported from the 'SPM25' (version 25.01.02)
        toolbox for 'MATLAB'.
