trawl_DExp {trawl}R Documentation

Evaluates the double exponential trawl function

Description

Evaluates the double exponential trawl function

Usage

trawl_DExp(x, w, lambda1, lambda2)

Arguments

x

the argument at which the double exponential trawl function will be evaluated

w

parameter in the double exponential trawl

lambda1

the parameter λ1\lambda_1 in the double exponential trawl

lambda2

the parameter λ2\lambda_2 in the double exponential trawl

Details

The trawl function is parametrised by parameters 0w10\leq w\leq 1 and λ1,λ2>0\lambda_1, \lambda_2 > 0 as follows:

g(x)=weλ1x+(1w)eλ2xz,\mboxforx0.g(x) = w e^{\lambda_1 x}+(1-w) e^{\lambda_2 xz}, \mbox{ for } x \le 0.

Value

The double exponential trawl function evaluated at x
