qbymc {qGaussian}

qbymc, a q value estimator founded upon medcouple.

Description

Given a random data set, the 'qbymc' uses the medcouple, a robust measure of tail weights, to yield a 'q' value, a characteristic entropic index of the q-gaussian distributions.

Usage

qbymc(x)

Arguments

x

numeric vector

Value

a number q < 3, and the standard error.
