dlngeom: logit-normal geometric distribution

In schmettow/LNB: (zero- truncated) logit-normal binomial distribution functions

Description

distribution functions (probability, quantile and hazard) for the logit-normal geometric distribution

Usage

dlngeom(x, m, s)
plngeom(x, m, s)
qlngeom(q, m, s)
hlngeom(x, m, s)

Arguments

x, q	vector of random variable realizations or quantiles
m	distribution parameter (central tendency)
s	distribution parameter (dispersion)

Details

The logit-normal geometric is created by imposing a logit-normal prior on the parameter p of the geometric distribution.

Value

probability (dlngeom), cumulative probabilty (qlngeom), quantile (qlngeom) or hazard rate (hlngeom)
