Robust Moments for the GLD

Description

Computes the first four robust moments for the Normal Inverse Gaussian Distribution.

Usage

sampleMED(x)
sampleIQR(x)
sampleSKEW(x)
sampleKURT(x)

Arguments

Value

All values for the *sample functions are numeric vectors: d* returns the density, p* returns the distribution function, q* returns the quantile function, and r* generates random deviates.

All values have attributes named "param" listing the values of the distributional parameters.
