## Detailed Description

### template<typename Precision>
struct TooN::RobustIII< Precision >

A reweighting class where the objective function tends to a fixed value, rather than infinity.

Note that this is not therefore a proper distribution since its integral is not finite. It is considerably more efficient than RobustI and II, since log() is not used.
