Hi,
we had some preliminary discussion about changing the
BinominalConfidenceInterval class in MATH-1086.
Right now the class provides some non-static methods to create various
ConfidenceIntervals, and I was proposing to change them to be static.
Another option would be to allow sub-classing by defining an interface
(or abstract base class) to create such an interval:
public interface BinomialConfidenceInterval {
ConfidenceInterval createInterval(int numberOfTrials,
int numberOfSuccesses,
double confidenceLevel);
}
With subclasses for the individual methods, e.g. Wilson or
NormalApproximation.
Phil suggested that we should still create static methods to create them
easily, e.g. in TestUtils.
