skewNormal {EvidenceSynthesis} R Documentation

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.
