Ultimately, though, we're interested in working from the observed distribution back to the underlying distribution. Fortunately, the combined recovery bias and distortion expression provides a simple way to do this:  \begin{equation}\label{eqn:n-Pact_from_n-Pobs}  n(P_{\rm act}) = -\left( -P_{\rm act}^{-1}\ \left(  \dfrac{P_{\rm max} - P_{\rm min}}{P_{\rm min}\ P_{\rm act}} min}\}  \right)\ \left( \frac{d}{dP_{\rm obs}} \right)_{P_{\rm obs} = P_{\rm act}} \bigg[ n(P_{\rm obs})\ P_{\rm obs}^2 \bigg]. \end{equation}
