%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'.
