In INLAvaan: Approximate Bayesian Latent Variable Analysis

Fit a skew normal distribution to a sample

Description

Fit a skew normal distribution to a sample

Usage

fit_skew_normal_samp(x)

Arguments

x	A numeric vector of sample data.

Details

Uses maximum likelihood estimation to fit a skew normal distribution to the provided numeric vector x.

Value

A list with fitted parameters:

• xi: location parameter

• omega: scale parameter

• alpha: shape parameter

• logC: log-normalization constant

• k: temperature parameter

• rsq: R-squared of the fit

Note that logC and k are not used when fitting from a sample.

Examples

x <- rnorm(100, mean = 5, sd = 1)
unlist(fit_skew_normal_samp(x))
