Fit Dirichlet or Generalized Dirichlet distribution to the dataframe of elicited conditional QPPs

Description

Fit Dirichlet or Generalized Dirichlet distribution to the dataframe of elicited conditional QPPs

Usage

fit_dir(df, id_col, spt_col, prb_col)

fit_gendir(df, id_col, spt_col, prb_col)

Arguments

df	data frame of conditional QPPs with 3 columns: category id, SPTs (probability triplets per category), values (probability value for Qdirichlet)
id_col	character name of the column containing category id
spt_col	character name of the column containing pribability triplets per category
prb_col	character name of the column containing values (probabilities for QDirichlet)

Value

data frame with 2(3) columns containing category id and the parameters of Dirichlet or Generalized Dirichlet distribution

Examples

df <- data.frame(id=rep(1:3, each=3),
                 spt=rep(0.25*1:3, 3),
                 values=c(7, 9, 12, 34, 41, 50, 5, 7.5, 15)/100)
 fit_dir(df, "id", "spt", "values")
 fit_gendir(df, "id", "spt", "values")
