|
y |
The data sample. |
mu |
mu is the location parameter. By default this is set to 0. |
delta |
delta is the scale parameter of the distribution. A default value of 1 has been set. |
alpha |
alpha is the tail parameter, with a default value of 1. |
beta |
beta is the skewness parameter, by default this is 0. |
lambda |
lambda is the shape parameter and dictates the shape that the distribution shall take. Default value is 1. |
param |
Parameters of the generalized hyperbolic distribution. |
xlab, ylab, main |
Plot labels. |
plot.it |
Logical. Should the result be plotted? |
line |
Add line through origin with unit slope. |
... |
Further graphical parameters. |
For qqghyp
and ppghyp
, a list with components:
x |
The x coordinates of the points that are to be plotted. |
y |
The y coordinates of the points that are to be plotted. |
