Overload List
| # | Signature | Description |
|---|---|---|
| 1 | procedure LogWeibullCDF(const X: TDenseMtxVec; a: Double; b: Double; const Res: TDenseMtxVec); | Log-Weibull CDF (vectorized). |
| 2 | function LogWeibullCDF(x: Double; a: Double; b: Double): Double; | Log-Weibull cumulative distribution function (CDF). |
Overload 1: procedure LogWeibullCDF(const X: TDenseMtxVec; a: Double; b: Double; const Res: TDenseMtxVec);
Log-Weibull CDF (vectorized).
| # | Name | Description |
|---|---|---|
| 1 | X | Defines distribution domain, real vector or matrix with real values. |
| 2 | a | Distribution location parameter, real positive value. |
| 3 | b | Distribution scale parameter, real positive value. |
| 4 | Res | After calculation stores the CDF calculated from X, a and b. Length and Complex properties of Res are adjusted automatically to match Length and Complex properties of X. |
Result: stored in self (calling object)
Overload 2: function LogWeibullCDF(x: Double; a: Double; b: Double): Double;
Log-Weibull cumulative distribution function (CDF).
| # | Name | Description |
|---|---|---|
| 1 | x | Function domain, real value. |
| 2 | a | Distribution location parameter, real value. |
| 3 | b | Distribution scale parameter, real positive value. |
Returns: Double - the log-Weibull cumulative distribution function (CDF) for value x using the parameters a and b. For b = 0 the result is NAN.
Remarks:
The log-Weibull cumulative distribution function is
CDF(x| a,b)=exp[-exp((a-x)/b)]
This equals the maximum Gumbel CDF with location a and scale b. Domain: x any real value, a any real value, scale b > 0; the result rises monotonically from 0 to 1. For b = 0 the result is NAN.
