clusterDiagGaussianNames {MixAll}R Documentation

Create a vector of diagonal Gaussian mixture model names.

Description

In a diagonal Gaussian mixture model, we assume that the variance matrices are diagonal in each cluster. Assumptions on the proportions and standard deviations give rise to 8 models:

  1. The proportions can be equal or free

  2. The standard deviations can be equal or free for all the variables

  3. The standard deviations can be equal or free for all the clusters

Usage

clusterDiagGaussianNames(
  prop = "all",
  sdInCluster = "all",
  sdBetweenCluster = "all"
)

clusterValidDiagGaussianNames(names)

Arguments

prop

A character string equal to "equal", "free" or "all". Default is "all".

sdInCluster

A character string equal to "equal", "free" or "all". Default is "all".

sdBetweenCluster

A character string equal to "equal", "free" or "all". Default is "all".

names

a vector of character

Details

The model names are summarized in the following array:

Model Name Proportions s.d. in variables s.d. in clusters
gaussian_p_sjk Equal Free Free
gaussian_p_sj Equal Free Equal
gaussian_p_sk Equal Equal Free
gaussian_p_s Equal Equal Equal
gaussian_pk_sjk Free Free Free
gaussian_pk_sj Free Free Equal
gaussian_pk_sk Free Equal Free
gaussian_pk_s Free Equal Equal

Value

A vector of character with the model names.

Examples

clusterDiagGaussianNames()
## same as c("gaussian_p_sk", "gaussian_pk_sk")
clusterDiagGaussianNames(prop="all", sdInCluster="equal", sdBetweenCluster= "free")
