distr_density {gasmodel}

Compute Density

Description

A function computing density or its logarithm of a given distribution.

Usage

distr_density(y, f, distr, param = NULL, par_link = NULL, trans = NULL)

Arguments

y

Observations. For an univariate distribution, a numeric vector. For a multivariate distribution, a numeric matrix with observations in rows or a numeric vector of a single observation.

f

Parameters. For the same parameters for all observations, a numeric vector. For individual parameters for each observation, a numeric matrix with rows corresponding to observations.

distr

A distribution.

param

A parametrization of the distribution.

par_link

An optional logical vector indicating whether the logarithmic/logistic link should be applied to restricted parameters in order to obtain unrestricted values. Defaults to keeping the original link for all parameters.

trans

An optional transformation of the density. The supported transformation is the logarithm of the density (trans = "log").

Value

The (transformed) density.

Examples

# Density of the negative binomial distribution
distr_density(y = c(1, 8, 5, 0, 0), f = c(13.50, 0.03), distr = "negbin")
