| Oct 30, 2015 at 20:48 | comment | added | Fabio | Mark, you are right! probably nonlinearity is playing a crucial role here and $f$ should be nonlinear monotonic. | |
| Oct 30, 2015 at 20:33 | comment | added | Mark Fischler | Not every monotonic function will work. Consider $f(x) = x$ so that $c_\lambda = \sum_i x_i - N\lambda$. Here, a set $\{c_\lambda\}$ determines nothing at all about the $x_i$, and even a map of $\lambda$ to $c_\lambda$ only determines the sum of the $x_i$ (assuming that map is self-consistent). | |
