trawl_DExp function

Evaluates the double exponential trawl function

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 $\lambda_1$ in the double exponential trawl
• lambda2: the parameter $\lambda_2$ in the double exponential trawl

Returns

The double exponential trawl function evaluated at x

Details

The trawl function is parametrised by parameters $0\leq w\leq 1$

and $\lambda_1, \lambda_2 > 0$ as follows:
