Implements org.apache.commons.math3.stat.interval.BinomialConfidenceInterval.createInterval.

Doc from org.apache.commons.math3.stat.interval.BinomialConfidenceInterval.createInterval.

Create a confidence interval for the true probability of success of an unknown binomial distribution with the given observed number of trials, successes and confidence level.

Preconditions:

  • numberOfTrials must be positive
  • numberOfSuccesses may not exceed numberOfTrials
  • confidenceLevel must be strictly between 0 and 1 (exclusive)

Parameters
numberOfTrials:int

number of trials

numberOfSuccesses:int

number of successes

confidenceLevel:double

desired probability that the true probability of success falls within the returned interval

Returns:ConfidenceInterval

Confidence interval containing the probability of success with probability confidenceLevel
