public class LogisticDistribution : ContinuousDistribution
Inheritance
Object  →  Distribution  →  ContinuousDistribution  →  LogisticDistribution

Remarks

The logistic distribution can be used to model growth. In many processes, the growth is slow at the beginning, picks up in the middle, and slows down again when approaching a saturation point.

The logistic distribution has two parameters: a LocationParameter and a ScaleParameter.

Example

Population growth and the market share of a new product can both be modeled using the logistic distribution.

Constructors

LogisticDistribution(Vector<Double>) Estimates the parameters of the distribution of a variable assuming it follows a logistic distribution.
LogisticDistribution(Double, Double) Constructs a new LogisticDistribution with the specified location and scale parameters.
LogisticDistribution(Vector<Double>, EstimationMethod) Estimates the parameters of the distribution of a variable assuming it follows a logistic distribution.
