Simulated sample from a skew-normal distribution

Description

A sample simulated from the SN(0,1,5) distribution with sample coefficient of skewness inside the admissible range (-0.9952719, 0.9952719) for the skew-normal family but maximum likelihood estimate on the frontier of the parameter space.

Usage

data(frontier)

Format

A numeric vector of length 50.

Source

Generated by a run of rsn(50, 0, 1, 5).

Examples

fit <- selm(frontier ~ 1)
plot(fit, which=2)
