Summary
Weibull cumulative distribution function (CDF).
Unit
Probabilities
Declaration
Procedure WeibullCDF(X: TDenseMtxVec; A, B: TSample; Res: TDenseMtxVec);
Description
Calculates the Weibull CDF for vector X using the parameters A and B. 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.
Declaration
Function WeibullCDF(x: TSample; a, b: TSample): TSample;
Result
the Weibull cumulative distribution function for value x using the parameters a and b. Value x must be greater or equal than zero and parameters a and b must be positive numbers, otherwise the result is NAN. The Weibull cumulative distribution function is defined by the following equation:

where I is the interval on which the Weibull CDF is not zero.
