Compute Dirichlet-DirichletGamma hyperparameters, using 'MLE' estimators

For the 'DirDirGamma' model. It computes an estimate using ML estimates of the parameters in each group.

fun_estimate_DirDirGamma_hyperparameter(
  df_background,
  col_source = "source",
  eps = 1e-12,
  convcrit = 1e-08
)

Arguments

df_background

dataframe with background data
col_source

name of the source column (default: 'source')
eps

convergence parameters for Dirichlet MLE (see: dirichlet.mle())
convcrit

convergence parameters for Dirichlet MLE (see: dirichlet.mle())

Value

a numeric vector for the estimated Dirichlet hyperparameter

Returns a list.
