DirichCat: Draw a full species name using a Categorical-Dirichlet scheme

In EcoFoG/vernabota: Association between vernacular and botanical names for Guyafor data

Draw a full species name using a Categorical-Dirichlet scheme

Description

This function draws a full species name for a given tree within the vector alphaV using a Categorical-Dirichlet scheme.

Usage

DirichCat(alphaV, Names, Vern)

Arguments

alphaV	vector alphaV obtained in the DrawBota function (posterior alpha for the given vernacular name, with all botanical name of Alpha)
Names	vector of all botanical name of Alpha
Vern	the vernacular name of the tree for which we want to get a full botanical name (character)

Details

This function performs the following steps:

• draw one vector in a Dirichlet distribution of shape parameters Vect

• draw one value in a Categorical distribution of parameter p the vector obtained from the Dirichlet (i.e draw one botanical name one time with the probability being the vector obtained from the Dirichlet)

• retrieve the botanical name corresponding to the non null value in this vector

Value

A botanical name obtained from a Dirichlet-Categorical association.
