dsubbo {Rsubbotools} | R Documentation |
Returns density from Subbotin Distribution
Description
The dsubbo
returns the density at point x for the
Subbotin distribution with parameters a
, b
, m
.
Usage
dsubbo(x, m = 0, a = 1, b = 2)
Arguments
x |
(numeric) - value in the range |
m |
(numeric) - location parameter. |
a |
(numeric) - scale parameter. Must be in the range |
b |
(numeric) - shape parameter. Must be in the range |
Details
The Subbotin distribution is a exponential power distribution controlled by three parameters, with formula:
f(x;a,b,m) = \frac{1}{A} e^{-\frac{1}{b} |\frac{x-m}{a}|^b}
with:
A = 2ab^{1/b}\Gamma(1+1/b)
where a
is a scale parameter, b
controls the tails (lower values
represent fatter tails), and m
is a location parameter.
Value
a vector containing the values for the densities.
