Fits a Dirichlet distribution based on the parameters of Beta distributions
fitdirichlet(..., plotBeta = FALSE, n.fitted = "opt")
a vector with the parameters for a Dirichlet distribution
named vectors with the distribution parameters shape1, shape2
if TRUE a ggplot of the densities are plotted
Method to fit the values
John J. Aponte
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
fitbeta
fitDirichlet
a <- fitbeta(0.3, 0.2, 0.4) c <- fitbeta(0.2, 0.1, 0.3) b <- fitbeta(0.5, 0.4, 0.6) fitdirichlet(cat1=a,cat2=b,cat3=c)
