The star OGF of ecld is the limiting OGF for small sigma.
It only depends on the normalized k and lambda.
Its dependency on sigma and mu is removed.
SGED is not supported yet.
Usage
ecld.ogf_star(object, ki)
ecld.ogf_star_hgeo(object, ki, order = 4)
ecld.ogf_star_exp(object, ki, order = 3)
ecld.ogf_star_gamma_star(object, ki, order = 6)
ecld.ogf_star_analytic(object, ki)
Arguments
object
an object of ecld class
ki
a numeric vector of log-strike
order
numeric, order of the hypergeometric series to be computed
