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:
The proportions can be equal or free.
The standard deviations can be equal or free for all the variables.
The standard deviations can be equal or free for all the clusters.

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 |
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 |
A vector of character with the model names.
