dALoD(y, mu, phi, alpha)

pALoD(q, mu, phi, alpha)

qALoD(beta, mu, phi, alpha)

rALoD(n, mu, phi, alpha)

Arguments

y, q

These are each a vector of quantiles.

mu

This is the location parameter μ.

phi

This is the scale parameter φ.

alpha

This is the index parameter α.

beta

This is a vector of probabilities.

n

This is the number of observations, which must be a positive integer that has length 1.

Value

dALoD provides the density, pALoD provides the cumulative distribution function, qALoD provides the quantile function, and rALoD generates a random sample from the quantile-based asymmetric logistic distribution. The length of the result is determined by n for rALoD, and is the maximum of the lengths of the numerical arguments for the other functions.
