Auxiliary formulas.

Formula	Range
$P (C) = \frac{T_{P} + F_{N}}{T_{P} + F_{N} + F_{P} + T_{N}}$	[0,1]
$P (C \| M) = \frac{T_{P}}{T_{P} + F_{P}}$	[0,1]
$\frac{P (C \| M)}{P (C)} = \frac{T_{P} \times (T_{P} + F_{N} + F_{P} + T_{N})}{(T_{P} + F_{P}) \times (T_{P} + F_{N})}$	[0,1]
$\frac{1 - P (C \| M)}{1 - P (C)} = \frac{F_{P} \times (T_{P} + F_{N} + F_{P} + T_{N})}{(T_{P} + F_{P}) \times (T_{N} + F_{P})}$	[0,1]
$I n f o (M) = - l o g_{\| Σ \|} P (M)$	[0, + ∞[
