Oapospois {VGAM} | R Documentation |
Density, distribution function, quantile function and random generation
for the one-altered positive-Poisson distribution with parameter pobs1
.
doapospois(x, lambda, pobs1 = 0, log = FALSE) poapospois(q, lambda, pobs1 = 0) qoapospois(p, lambda, pobs1 = 0) roapospois(n, lambda, pobs1 = 0)

Probability of (an observed) one, called pobs1.
The default value of |
The probability function of Y is 1 with probability pobs1
,
else a 1-truncated
positive-Poisson(lambda)
distribution.
doapospois
gives the density and
poapospois
gives the distribution function,
qoapospois
gives the quantile function, and
roapospois
generates random deviates.
The argument pobs1
is recycled to the required length, and
must have values which lie in the interval [0,1].
