Joel is having me change them to \#12/2.

|
|
Suppose a true cost model,
|
|
accounting for all relevant information available at time $t$.
|
|
|
|
$C(t)$ returns a distribution whose [scale](https://en.wikipedia.org/wiki/Scale_parameter)
|
|
decreases with $t$, and $C(0)$ maps to a single value.
|
|
$t>0$ is time until the final payment.
