Yule-Simon Distribution
Description
Density, distribution function, quantile function and random generation for the Yule-Simon distribution.
Usage
dyules(x, shape, log = FALSE)
pyules(q, shape, lower.tail = TRUE, log.p = FALSE)
qyules(p, shape)
ryules(n, shape)
Arguments
x , q , p , n |
Same meaning as in |
shape |
See |
log , lower.tail , log.p |
Details
See yulesimon
, the VGAM family function
for estimating the parameter,
for the formula of the probability density function
and other details.
Value
dyules
gives the density,
pyules
gives the distribution function,
qyules
gives the quantile function, and
ryules
generates random deviates.
Note
Numerical problems may occur with
qyules()
when p
is very close to 1.
