distr_var function

Compute Variance

A function computing variance for a given distribution.

distr_var(f, distr, param = NULL, par_link = NULL)

Arguments

• 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.

Returns

The variance.

Examples

# Variance for the negative binomial distribution
distr_var(f = c(13.50, 0.03), distr = "negbin")
