In admix: Package Admix for Admixture (aka Contamination) Models

Extractor for known component(s) in admixture model(s)

Description

Get the known component of the admixture model considered for estimation, test, or clustering.

Usage

get_known_component(x)

Arguments

x	An object of class admix_estim, gaussianity_test, orthobasis_test, IBM_test, or admix_cluster.

Details

This is a generic extractor, providing with the same information whatever the object class.

Value

A list providing information on the known component (distribution, parameters).

Examples

## Simulate a two-component Gaussian mixture:
mixt1 <- twoComp_mixt(n = 380, weight = 0.7,
                      comp.dist = list("norm", "norm"),
                      comp.param = list(list("mean" = -2, "sd" = 0.5),
                                        list("mean" = 0, "sd" = 1)))
data1 <- get_mixture_data(mixt1)
admixMod1 <- admix_model(knownComp_dist = mixt1$comp.dist[[2]],
                         knownComp_param = mixt1$comp.param[[2]])
## Estimate the unknown quantities:
x <- admix_estim(samples = list(data1), admixMod = list(admixMod1), est_method = "BVdk")
## Extract the information about the known component:
get_known_component(x)
