        """Calculate and save the p-values of the :math:`\\Lambda`-motifs.

        For each node couple in the bipartite layer specified by ``bip_set``,
        calculate the p-values of the corresponding :math:`\\Lambda`-motifs
        according to the link probabilities in the biadjacency matrix of the
        BiCM null model.

        The results can be saved either as a binary ``.npy`` or a
        human-readable ``.csv`` file, depending on ``binary``.

        .. note::

            * The total number of p-values that are calculated is split into
              ``num_chunks`` chunks, which are processed sequentially in order
              to avoid memory allocation errors. Note that a larger value of
              ``num_chunks`` will lead to less memory occupation, but comes at
              the cost of slower processing speed.

            * The output consists of a one-dimensional array of p-values. If
              the bipartite layer ``bip_set`` contains ``n`` nodes, this means
              that the array will contain :math:`\\binom{n}{2}` entries. The
              indices ``(i, j)`` of the nodes corresponding to entry ``k`` in
              the array can be reconstructed using the method
              :func:`BiCM.flat2_triumat_idx`. The number of nodes ``n``
              can be recovered from the length of the array with
              :func:`BiCM.flat2_triumat_dim`

            * If ``binary == False``, the ``filename`` should end with
              ``.csv``. If ``binary == True``, it will be saved in binary NumPy
              ``.npy`` format and the suffix ``.npy`` will be appended
              automatically. By default, the file is saved in binary format.
