dPGaGEV {PGaGEV} | R Documentation |
The probability density function (PDF) of the power Garima-generalized extreme value distribution(PGaGEV).
Description
This function calculated the PDF of PGaGEV distribution.
Usage
dPGaGEV(x, mu, sigma, xi, a, b, c)
Arguments
x |
vector of quantiles.There are three cases as follows: 1) if xi>0, x=[(mu-sigma)/xi,Inf].2) if xi=0, x=[-Inf,Inf].3) if xi<0, x=[-Inf,(mu-sigma)/xi]. |
mu |
location parameter. |
sigma |
scale parameter number 1. |
xi |
shape parameter number 1. |
a |
scale parameter number 2. |
b |
scale parameter number 3. |
c |
shape parameter number 2. |
Details
