WeibullReliabilityFunction (jreliability v2.0 API)

java.lang.Object
- org.jreliability.function.SequentialFunction
- - org.jreliability.function.common.WeibullReliabilityFunction

All Implemented Interfaces:

Function, ReliabilityFunction
```
public class WeibullReliabilityFunction
extends SequentialFunction
implements ReliabilityFunction
```
The WeibullReliabilityFunction represents the 2-parameter Weibull reliability function
R(x) = 1 - F(x) = e^-((x / nu)^beta)) = e^-((alpha * x)^beta))}
with alpha, beta > 0.
While the parameter alpha = 1 / nu scales the ReliabilityFunction and, thus, somehow corresponds to the failure-rate lambda, the beta parameter determines the shape of the ReliabilityFunction.
