AB: Two-Group Permutation Test

In peramo: Permutation Tests for Randomization Model

Two-Group Permutation Test

Description

AB performs A/B testing for two-group experiments.

Usage

AB(a, b, rand = 9999, seed = 1)

Arguments

a	the measurement of responses of the first group.
b	the measurement of responses of the second group.
rand	an integer, the number of randomization samples. The default value is 9999.
seed	an integer, the seed for random number generation. Setting a seed ensures the reproducibility of the result. See set.seed for more details.

Value

AB returns an one-row data frame with 6 columns:

nA	the sample size of the first group.
mean.A	the mean responses of the first group.
nB	the sample size of the second group.
mean.B	the mean responses of the second group.
mean.dif	the difference between two mean responses.
pval	the p-value.
