densityratio (version 0.2.1)

summary.kliep: Extract summary from kliep object, including two-sample significance test for homogeneity of the numerator and denominator samples

Description

Extract summary from kliep object, including two-sample significance test for homogeneity of the numerator and denominator samples

Usage

# S3 method for kliep
summary(
  object,
  test = FALSE,
  n_perm = 100,
  parallel = FALSE,
  cluster = NULL,
  min_pred = 1e-06,
  ...
)

Value

Summary of the fitted density ratio model

Arguments

object

Object of class kliep

test

logical indicating whether to statistically test for homogeneity of the numerator and denominator samples.

n_perm

Scalar indicating number of permutation samples

parallel

logical indicating to run the permutation test in parallel

cluster

NULL or a cluster object created by makeCluster. If NULL and parallel = TRUE, it uses the number of available cores minus 1.

min_pred

Scalar indicating the minimum value for the predicted density ratio values (used in the divergence statistic) to avoid negative density ratio values.
