| Method Summary | |
| abstract protected double | getDomainLowerBound(double p)
Access the domain value lower bound, based on p, used to
bracket a CDF root. | | abstract protected double | getDomainUpperBound(double p)
Access the domain value upper bound, based on p, used to
bracket a CDF root. | | abstract protected double | getInitialDomain(double p)
Access the initial domain value, based on p, used to
bracket a CDF root. | | public double | inverseCumulativeProbability(double p)
For this distribution, X, this method returns the critical point x, such
that P(X < x) = p. |
| AbstractContinuousDistribution | | protected AbstractContinuousDistribution()(Code) | | Default constructor.
|
| getDomainLowerBound | | abstract protected double getDomainLowerBound(double p)(Code) | | Access the domain value lower bound, based on p, used to
bracket a CDF root. This method is used by
AbstractContinuousDistribution.inverseCumulativeProbability(double) to find critical values.
Parameters:
p - the desired probability for the critical value domain value lower bound, i.e.P(X < lower bound) < p |
| getDomainUpperBound | | abstract protected double getDomainUpperBound(double p)(Code) | | Access the domain value upper bound, based on p, used to
bracket a CDF root. This method is used by
AbstractContinuousDistribution.inverseCumulativeProbability(double) to find critical values.
Parameters:
p - the desired probability for the critical value domain value upper bound, i.e.P(X < upper bound) > p |
| inverseCumulativeProbability | | public double inverseCumulativeProbability(double p) throws MathException(Code) | | For this distribution, X, this method returns the critical point x, such
that P(X < x) = p.
Parameters:
p - the desired probability x, such that P(X < x) = p
throws:
MathException - if the inverse cumulative probability can not becomputed due to convergence or other numerical errors.
throws:
IllegalArgumentException - if p is not a validprobability. |
