The CDF of the loglogistic distribution

Description

The CDF of the loglogistic distribution

Usage

pllogis(q, pda, pdb)

Arguments

q

a numeric vector of quantiles

pda

the α\alpha parameter

pdb

the β\beta parameter

Details

There are several common parameterizations of the loglogistic distribution. The one used here gives the following:

CDF

Pr(X <= x) = 1/(1 + (x/β\beta)^-α\alpha)

PDF

Pr(X = x) = (α\alpha/β\beta) * (x/β\beta)^(α\alpha - 1)/(1 + (x/β\beta)^α\alpha)^2

Value

Pr(X <= q | pda, pdb)
