gammaNames: Build a vector of gamma model names.

Description

In a gamma model, we can assume that the shapes are equal in each/all cluster(s) or not. We can also assume that the scales are equal in each/all cluster(s) or not.

Usage

gammaNames(prop = "all", shapeInCluster = "all",
  shapeBetweenCluster = "free", scaleInCluster = "all",
  scaleBetweenCluster = "all")

Arguments

prop

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

shapeInCluster

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

shapeBetweenCluster

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

scaleInCluster

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

scaleBetweenCluster

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

Value

• A vector of character with the model names.

Details

Some configuration are impossibles. If the shapes are equal between all the clusters, then the scales cannot be equal between all the clusters. Conversely if the scales are equal between all the cluster, then the shapes cannot be equal between all the clusters.

This gives rise to 24 models:

1. The proportions can be equal or free.

The shapes can be equal or free in each clusters. The shapes can be equal or free between all clusters. The scales can be equal or free for each clusters. The scales can be equal or free between all clusters.

Examples

gammaNames()
gammaNames("all", "equal", "free", "free", "equal") # same as c("gamma_p_ak_bj", "gamma_pk_ak_bj")
