private static double hackyAdjuster ( final double f ) { final double tmp = Math . sqrt ( 1.0 - f ) ; return ( f <= 0.5 ) ? tmp : tmp + ( 0.01 * ( f - 0.5 ) ) ; }
This hackyAdjuster is tightly coupled with the width of the confidence interval normally specified with number of standard deviations . To simplify this interface the number of standard deviations has been fixed to 2 . 0 which corresponds to a confidence interval of 95% .
