Probabilities::LogisticCDFInv Function

Overload List

#SignatureDescription
1double LogisticCDFInv(double p, double m, double b);Logistic distribution point percent function (PPF).
2void LogisticCDFInv(TDenseMtxVec *P, double m, double b, TDenseMtxVec *Res);Logistic distribution PPF (vectorized).

Overload 1: double LogisticCDFInv(double p, double m, double b);

Logistic distribution point percent function (PPF).

#NameTypeDescription
1pdoubleProbability, real value on closed interval [0,1].
2mdoubleDistribution location parameter, real value.
3bdoubleDistribution scale parameter, real positive value.

Returns: the Logistic distribution point percent function (PPF) for probability p using the parameters m and b. For b <= 0 the result is NAN; for p = 0 the result is -INF and for p = 1 the result is +INF.

Remarks:

The inverse logistic cumulative distribution function (quantile) is

CDF^(-1)(p| m,b)=m-b ln(1/p-1)

Domain: probability p in [0,1], m any real value, scale b > 0. The boundary cases return p = 0 -> -INF and p = 1 -> +INF. For b <= 0 the result is NAN.

Overload 2: void LogisticCDFInv(TDenseMtxVec *P, double m, double b, TDenseMtxVec *Res);

Logistic distribution PPF (vectorized).

#NameTypeDescription
1PTDenseMtxVec *Defines distribution probabilities, real vector or matrix with values within closed interval [0,1].
2mdoubleDistribution location parameter, real value.
3bdoubleDistribution scale parameter, real positive value.
4ResTDenseMtxVec *After calculation stores the PPF calculated from P, m and b. Length and Complex properties of Res are adjusted automatically to match Length and Complex properties of P.
