ecld.solve: Analytic solution for $y(x)$ in lambda distribution

Description

Analytic solution for $y(x)$ if available. $ecld.laplace_B$ is a utility function for the slopes of a skew Laplace distribution at lambda=2: $B^+$ and $B^-$ with $B^0/2=B^{+}+B^{-}$. If sigma is provided, B notation is expanded for IMGF where $B^{+}_{\sigma} B^{-}_{\sigma} = \exp(\mu_D)$. SGED is supported.

Usage

ecld.solve(a, b, ...)
ecld.laplace_B(beta, sgn = 0, sigma = 0)

Arguments

a

an object of ecld class

b

a vector of $x$ values

...

Not used. Only here to match the generic signature.

beta

the skew parameter

sgn

sign of $-1, 0, +1$

sigma

the scale parameter, optional

Value

A vector for $y(x)$

Examples

ld <- ecld(sigma=0.01*ecd.mp1)
x <- seq(-0.1, 0.1, by=0.01)
ecld.solve(ld,x)
