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 \alpha parameter

pdb

the \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/\beta)^-\alpha)

PDF

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

Value

Pr(X <= q | pda, pdb)
