[borrowed from actuar]:
The (Single-parameter) Pareto distribution with parameter shape
= a has density:
f(x) = a b^a/x^(a + 1)
for x > b, a > 0 and b > 0.
Although there appears to be two parameters, only shape
is a true
parameter. The value of min
= b must be set in
advance.
Objects can be created by calls of the form new("Pareto", shape, Min)
.
More frequently they are created via the generating function
Pareto
