The skew normal function to approximate a log likelihood function

Description

The skew normal function to approximate a log likelihood function

Usage

skewNormal(x, mu, sigma, alpha)

Arguments

x	The log(hazard ratio) for which to approximate the log likelihood.
mu	The position parameter.
sigma	The scale parameter.
alpha	The skew parameter.

Details

The skew normal function. When alpha = 0 this function is the normal distribution.

Value

The approximate log likelihood for the given x.
