Unprotect[InverseFunction]
InverseFunction[Erf] = Statistics`InverseStatisticalFunctions`InverseErf
InverseFunction[Erf, 2, 2] = InverseErf
Protect[InverseFunction]


Note that once the context of InverseErf has been established (either by
reading in the package or refering to InverseErf by its full name
Statistics`InverseStatisticalFunctions`InverseErf) further references
to it can be made as simply InverseErf.
