ecop.polyfit_option

length-one numeric, the suggested cusp location

k.cusp

numeric, vector of log-strike to evaluate the poly fit

k.new

length-one numeric, specifying the degree of poly fit for the left tail

degree.left

length-one numeric, specifying the degree of poly fit for the right tail

degree.right


The poly fits on logarithm of option prices are performed for each side 
of the suggested cusp (specified by <code>k.cusp</code>).
This utiility is used mainly to remove the market data noise for 
the calculation of log-slope of option prices.


ecop

An implementation of the univariate elliptic distribution
and elliptic option pricing model. It provides detailed functionality
and data sets for the distribution and modelling.
Especially, it contains functions for the computation of
density, probability, quantile, fitting procedures, option prices,
volatility smile. It also comes with sample financial data, and plotting routines.
