Description

Parameter estimation in the quantile-based asymmetric Laplace distribution by using method of moments is studied in Gijbels et al. (2019a).

Usage

1
momALaD(y, alpha = NULL)

Arguments

y

This is a vector of quantiles.

alpha

This is the index parameter α. If α is unknown, the it should be NULL which is default option. In this case, the sample skewness will be used to estimate α. If α is known, then the value of α has to be specified in the function.

Value

momALaD provides the method of moments estimates of the unknown parameters of the distribution.
