Overload List
| # | Signature | Description |
|---|---|---|
| 1 | procedure LogWeibullCDFInv(const P: TDenseMtxVec; a: Double; b: Double; const Res: TDenseMtxVec); | Log-Weibull distribution PPF (vectorized). |
| 2 | function LogWeibullCDFInv(p: Double; a: Double; b: Double): Double; | Log-Weibull distribution point percent function (PPF). |
Overload 1: procedure LogWeibullCDFInv(const P: TDenseMtxVec; a: Double; b: Double; const Res: TDenseMtxVec);
Log-Weibull distribution PPF (vectorized).
| # | Name | Description |
|---|---|---|
| 1 | P | Defines distribution probabilities, real vector or matrix with values within closed interval [0,1]. |
| 2 | a | Distribution location parameter, real positive value. |
| 3 | b | Distribution scale parameter, real positive value. |
| 4 | Res | After calculation stores the PPF calculated from P, a and b. Length and Complex properties of Res are adjusted automatically to match Length and Complex properties of P. |
Result: stored in self (calling object)
Overload 2: function LogWeibullCDFInv(p: Double; a: Double; b: Double): Double;
Log-Weibull distribution point percent function (PPF).
| # | Name | Description |
|---|---|---|
| 1 | p | Probability, real value on closed interval [0,1]. |
| 2 | a | Distribution location parameter, real value. |
| 3 | b | Distribution scale parameter, real positive value. |
Returns: Double - the Log-Weibull distribution point percent function (PPF) for probability p using the parameters a and b. p must lie in [0,1], otherwise the result is NAN.
Remarks:
The inverse log-Weibull cumulative distribution function (quantile) is
CDF^(-1)(p| a,b)=a-b ln(-ln p)
Domain: probability p in [0,1], a any real value, scale b > 0. For p < 0 or p > 1 the result is NAN.
