Description
The number of Dyck paths above the lattice path given by a binary word.
One may treat a binary word as a lattice path starting at the origin and treating $1$'s as steps $(1,0)$ and $0$'s as steps $(0,1)$. Given a binary word $w$, this statistic counts the number of lattice paths from the origin to the same endpoint as $w$ that stay weakly above $w$.
See St001312Number of parabolic noncrossing partitions indexed by the composition. for this statistic on compositions treated as bounce paths.
Code
def lattice_paths_above_boundary(B):
    B = list(B)
    if sum(B) == 0:
        return [B]
    else:
        paths = [ B[:1] + p for p in lattice_paths_above_boundary(B[1:]) ]
        if B[0] == 0:
            i = B.index(1)
            B = B[:i] + B[i+1:]
            paths.extend( [ [1] + p for p in lattice_paths_above_boundary(B) ] )
        return paths

def statistic(w):
    return len(lattice_paths_above_boundary(w))
