ReliabilityProblem31¶
- class ReliabilityProblem31(threshold=0.0, mu=[0.0, 0.0], sigma=[1.0, 1.0])¶
Methods
Return the beta of the reliability problem.
getEvent
()Return the event.
getName
()Return the name of the problem.
Return the probability.
Convert the object into a string, with full details.
- __init__(threshold=0.0, mu=[0.0, 0.0], sigma=[1.0, 1.0])¶
Creates a reliability problem RP31.
The event is {g(X) < threshold} where
g(x1, x2) = 2 - x2 + 256 * x1^4
We have x1 ~ Normal(mu[0], sigma[0]) and x2 ~ Normal(mu[1], sigma[1]).
- Parameters:
- thresholdfloat
The threshold.
- musequence of floats
The list of two items representing the means of the gaussian distributions.
- sigmafloat
The list of two items representing the standard deviations of the gaussian distributions.
- computeBeta()¶
Return the beta of the reliability problem.
This is the quantile of the probability of a standard gaussian distribution.
- Parameters:
- None.
- Returns:
- beta: float
The beta of the problem.
- getEvent()¶
Return the event.
- Parameters:
- None.
- Returns:
- event: ot.ThresholdEvent
The event.
- getName()¶
Return the name of the problem.
- Parameters:
- None.
- Returns:
- name: str
The name of the problem.
- getProbability()¶
Return the probability.
- Parameters:
- None.
- Returns:
- probability: float
The probability of the event.
- toFullString()¶
Convert the object into a string, with full details.
- Parameters:
- None.
- Returns:
- s: str
The string of the problem.
