dztplnm {ztpln} | R Documentation |
The zero-truncated compund poisson-lognormal distributions mixture
Description
Density function and random generation for Zero-Truncated
Poisson Lognormal distribution with parameters mu
, sig
, and theta
.
Usage
dztplnm(x, mu, sig, theta, log = FALSE, type1 = TRUE)
rztplnm(n, mu, sig, theta, type1 = TRUE)
Arguments
x |
vector of (non-negative integer) quantiles. |
mu |
vector of mean of lognormal distribution in sample. |
sig |
vector standard deviation of lognormal distribution in sample. |
theta |
vector of mixture weights |
log |
logical; if TRUE, probabilities p are given as log(p). |
type1 |
logical; if TRUE, Use type 1 ztpln else use type 2. |
n |
number of random values to return. |
Details
Type 1 ZTPLN truncates zero based on Poisson-lognormal distribution and
type 2 ZTPLN truncates zero based on zero-truncated Poisson distribution.
For mathematical details, please see vignette("ztpln")
Value
dztplnm gives the (log) density and rztplnm generates random variates. function, qpois gives the quantile function, and rpois generates random deviates.
