Description

Mean, variance, skewness, kurtosis and moments about the location parameter (i.e., αth quantile) of the quantile-based asymmetric logistic distribution defined in Gijbels et al. (2019a) useful for quantile regression with location parameter equal to μ, scale parameter φ and index parameter α.

meanALoD(mu, phi, alpha)

varALoD(mu, phi, alpha)

skewALoD(alpha)

kurtALoD(alpha)

momentALoD(phi, alpha, r)

Arguments

mu

This is the location parameter μ.

phi

This is the scale parameter φ.

alpha

This is the index parameter α.

r

This is a value which is used to calculate the rth moment about μ.

Value

meanALoD provides the mean, varALoD provides the variance, skewALoD provides the skewness, kurtALoD provides the kurtosis, and momentALoD provides the rth moment about the location parameter μ of the quantile-based asymmetric logistic distribution.
