  Effective quantum field theories that allow for the possibility of Lorentz
symmetry violation can sometimes also include redundancies of description in
their Lagrangians. Explicit calculations in a Lorentz-violating generalization
of Yukawa theory show that when this kind of redundancy exists, different
renormalization schemes may lead to different expressions for the
renormalization group $\beta$-functions, even at only one-loop order. However,
the renormalization group scaling of physically observable quantities appears
not to share this kind of scheme dependence.
