Class ConfidenceInterval

java.lang.Object
de.uka.ipd.sdq.statistics.estimation.ConfidenceInterval
public class ConfidenceInterval extends Object
Represents a confidence interval. Whether one confidence interval contains another can be checked by using the contains(ConfidenceInterval) method.

  • Constructor Details

    • ConfidenceInterval

      public ConfidenceInterval(double mean, double lowerBound, double upperBound, double level)
      Constructs a confidence interval around the specified mean, having bounds lowerBound and upperBound.
      Parameters:
      mean - the center of the confidence interval
      lowerBound - the confidence interval's lower bound
      upperBound - the confidence interval's upper bound
      level - the confidence level. Use values between 0 and 1. For instance use 0.95 to estimate the 95% confidence interval.
      noOfObservations - the number of observations this confidence interval is constructed from

    • ConfidenceInterval

      public ConfidenceInterval(double mean, double halfWidth, double level)
      Constructs a confidence interval around the specified mean having width (2 * mean * halfWidth).
      Parameters:
      mean - the center of the confidence interval
      halfWidth - the relative half-width. Use values between 0 and 1. For instance use 0.1 in order to specify a 10% half-width.
