trawl_supIG {trawl} | R Documentation |
Evaluates the supIG trawl function
trawl_supIG(x, delta, gamma)
x |
the argument at which the supIG trawl function will be evaluated |
delta |
the parameter |
gamma |
the parameter |
The trawl function is parametrised by the two parameters \delta
\geq 0
and \gamma \geq 0
as follows:
gd(x) =
(1-2x\gamma^{-2})^{-1/2}\exp(\delta \gamma(1-(1-2x\gamma^{-2})^{1/2})),
\mbox{ for } x \le 0.
It is assumed that \delta
and \gamma
are
not simultaneously equal to zero.
