S\(\alpha\)S Point5 Distribution Functions

Functions to compute the probability density function, cumulative distribution function, and quantile function for the S\(\alpha\)S Point5 distribution.

Usage

saspoint5_distribution(location = 0, scale = 1)

saspoint5_pdf(x, location = 0, scale = 1)

saspoint5_lpdf(x, location = 0, scale = 1)

saspoint5_cdf(x, location = 0, scale = 1)

saspoint5_lcdf(x, location = 0, scale = 1)

saspoint5_quantile(p, location = 0, scale = 1)

Arguments

location

location parameter (default is 0)

scale

scale parameter (default is 1)

x

quantile

p

probability (0 <= p <= 1)

Value

A single numeric value with the computed probability density, log-probability density, cumulative distribution, log-cumulative distribution, or quantile depending on the function called.
