1 Erratum to: Bull Math Biol DOI 10.1007/s11538-013-9847-0

The authors note that due to a printer’s error, in the text immediately following Eq. (2a), \({\mathbf{F}(\mathbf{X}) = (\mathbf{f}(\mathbf{x}), \dots , \mathbf{f}(\mathbf{x}))}\) should have read \({\mathbf{F}(\mathbf{x}) = (\mathbf{f}(\mathbf{x}_1), \dots , \mathbf{f}(\mathbf{x}_N))}\).

They also note that, due to a change in notation during copy editing, the same notation \(\mathbf{x}\) has inadvertently been used for the (\(\textit{dN}\))-dimensional argument of \(P\) and the \(d\)-dimensional argument of \(p\); see for example Eq. (4) and the text immediately before it.
