Robust moments for the GLD

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

Usage

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

Arguments

x

numeric vector, the sample values.

Value

a named numerical value. The name is one of MED, IQR, SKEW, or KURT, obtained by dropping the sample prefix from the name of the corresponding function.
