fitdirichlet {convdistr}R Documentation

Fits a Dirichlet distribution,

Description

Fits a Dirichlet distribution based on the parameters of Beta distributions

Usage

fitdirichlet(..., plotBeta = FALSE, n.fitted = "opt")

Arguments

...

named vectors with the distribution parameters shape1, shape2

plotBeta

if TRUE a ggplot of the densities are plotted

n.fitted

Method to fit the values

Details

Each one of the arguments is a named vector with values for shape1, shape2. Values from fitbeta are suitable for this. This is a wrap of fitDirichlet

Value

a vector with the parameters for a Dirichlet distribution
