LogLogistic {gestate} | R Documentation |
This creates a Curve object for a Log-logistic distribution.
Curve objects contain all necessary information to describe a distribution, including functions and parameters describing it.
See Details for information on parameterisation.
LogLogistic(theta, eta)
theta |
Scale parameter for Log-logistic distribution. |
eta |
Shape parameter for Log-logistic distribution. |
The log-logistic distribution has parameterisation:
f(x) = eta (theta^beta) x^(eta-1) (theta^eta + x^eta)^-2
F(x) = (x^eta) /(theta^eta+x^eta)
