| Synopsis
| This function converts a probability expressed in terms
of standard deviations to a Score (-10*log10(Prob)).
This is done in such a way that very large values can be handled
with precision and without causing overflow/underflow.
Formally, a Score is defined as: |
| |
|
| Score = -10 * log10( Prob{ Normal(0,1) < s } ) |
| Examples
| > Std_Score( -30 );
1973.0921
> Std_Score( +30 );
2.131e-197
