  The ontological models framework distinguishes $\psi$-ontic from
$\psi$-epistemic wavefunctions. It is, in general, quite straightforward to
categorize the wave-function of a certain quantum theory. Nevertheless, there
has been a debate about the ontological status of the wave-function in the
statistical interpretation of quantum mechanics: is it $\psi$-epistemic and
incomplete or $\psi$-ontic and complete? I will argue that the wavefunction in
this interpretation is best regarded as $\psi$-ontic and incomplete.
