question: private static double hackyAdjuster ( double f ) { double tmp = Math . sqrt ( 1.0 - f ) ; return ( f <= 0.5 ) ? tmp : tmp + ( 0.01 * ( f - 0.5 ) ) ; }
target:  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%.
