Bloch and Okounkov introduced an $n$-point correlation function on the fermionic Fock space and found a closed formula in terms of theta functions. This function affords several distinguished interpretations and in particular can be formulated as correlation functions on irreducible $hat{gl}_infty$-modules of level one. These correlation functions have been generalized for irreducible integrable modules of $hat{gl}_infty$ and its classical Lie subalgebras of positive levels by the authors. In this paper we extend further these results and compute the correlation functions as well as the $q$-dimensions for modules of $hat{gl}_infty$ and its classical subalgebras at negative levels.
