UniformNormalTails: Density and CDF for Uniform Distribution with Normal tails

Description

Density function and cumulative distribution function for a Uniform density with Normal tails. Introduced in Rufibach et al (2016a) as pessimistic distribution to compute Bayesian Predictive Power.

Usage

dUniformNormalTails(x, mu, width, height)
pUniformNormalTails(x, mu, width, height)

Arguments

x

Vector of quantiles.

mu

Mean of the pessimistic prior.

width

Width of the flat part of the prior.

height

Height of the flat part of the prior.

Value

Density at x.
