Probabilities
Declaration
Function FatigueLifePDF(x: TSample; mu, gamma, beta: TSample): TSample;
| Parameter | Description |
|---|---|
| x | Defines distribution parameter, valid on (mu,INF) interval. |
| mu | Defines distribution location parameter. |
| gamma | Defines distribution shape parameter. gamma must be a positive scalar. |
| beta | Defines distribution scale parameter. beta must be a positive scalar. |
Result
the Fatigue life probability density function (PDF)evaluated at x using the parameters gamma, mu and beta. Gamma and beta must be positive scalars and x>mu, otherwise an exception is raised.Description
Calculates the "Fatigue life" probability density function, defined by the equation:
The fatigue life distribution is also commonly known as the Birnbaum-Saunders distribution. Please note that there are several alternative formulations of the fatigue life distribution in the literature.
Parameters:
- mu: (-INF,INF)
- gamma: (0,INF)
- beta: (0,INF)

Procedure FatigueLifePDF(X: TDenseMtxVec; mu, gamma, beta: TSample; Res: TDenseMtxVec);
Description
Calculates the Fatigue life PDF for vector X using the parameters mu,gammma and beta. The results are stored in vector Res. The Res Length and Complex properties are adjusted automatically. If vector X is complex, an exception is raised.| Copyright 2008 Dew Research |
