Extract Standard Deviations of Mixture Components

Extract Standard Deviations of Mixture Components

mix_sigmas(x)

Arguments

x

A mixture distributional object

Value

numeric or list object

Details

If a distributional object that is a mixture of two or more normal distributions is read in, the function will return a numeric object with the standard deviations of each normal component. If the distributional object is a mixture of two or more multivariate normal distributions, the function will return a list with the covariance matrices of each multivariate normal component.

Examples

library(distributional)
mix_norm <- dist_mixture(comp1 = dist_normal(1, 10),
                         comp2 = dist_normal(1.5, 12),
                         weights = c(.5, .5))
mix_sigmas(mix_norm)
#> comp1 comp2 
#>    10    12
