Yule-Simon Distribution
Density, distribution function, quantile function and random generation for the Yule-Simon distribution.
dyules(x, shape, log = FALSE) pyules(q, shape, lower.tail = TRUE, log.p = FALSE) qyules(p, shape) ryules(n, shape)
x, q, p, n |

See yulesimon, the VGAM family function
for estimating the parameter,
for the formula of the probability density function and other details.
dyules gives the density,
pyules gives the distribution function,
qyules gives the quantile function, and
ryules generates random deviates.
Numerical problems may occur with
qyules() when p is very close to 1.
