question: @ Override public double confSmallM ( double totalWeight , double delta ) { double term = Math . log ( 4.0d / delta ) / ( 2.0d * totalWeight ) ; return Math . pow ( term , 1.5d ) + 3.0d * term + 3.0d * Math . sqrt ( term ) ; }
target:  Calculate confidence intervall without a specific rule for small m.
