Remarks

The log-logistic distribution, sometimes called the Fisk distribution, is used in survival analysis for events which occur with decreasing likelihood in time.

The log-logistic distribution has three parameters: a a LocationParameter, a ScaleParameter and a ShapeParameter. The location parameter is optional. THe scale and shape parameters must be positive.

Examples

The mortality from cancer following diagnosis or treatment can be modeled with the log-logistic distribution. In economics, the log-logistic distribution has been used to model the distribution of income.
