Summary
Logistic cumulative distribution function (CDF).Unit
Probabilities
Declaration
Procedure LogisticCDF(X: TDenseMtxVec; m, b: TSample; Res: TDenseMtxVec);
Description
Calculates the Logistic CDF for all X elements using the parameters Mu and Sigma. The results are stored in Res. It's size and Complex properties are adjusted automatically. If X is complex, an exception is raised.Declaration
Function LogisticCDF(x, m, b: TSample): TSample;
Result
the logistic cumulative distribution function (CDF) for value x using the parameters m and b. Both parameters must be positive, otherwise the result is NAN. The logistic cumulative distribution function is defined by the following equation:
The result of LogisticCDF is the probability that a single observation from a logistic distribution with parameters m and b will fall in the interval [-infinity,x].
