aihuman provides statistical methods for analyzing experimental evaluation of the causal impacts of algorithmic recommendations on human decisions developed by Imai, Jiang, Greiner, Halen, and Shin (2023).
The data used for this paper, and made available here, are interim, based on only half of the observations in the study and (for those observations) only half of the study follow-up period. We use them only to illustrate methods, not to draw substantive conclusions.
You can install the development version of aihuman from GitHub with:
# install.packages("devtools")
devtools::install_github("sooahnshin/aihuman")The main functions in this package are as follows:

may use CalAPCEparallel() instead of CalAPCE()
throughout the analysis.
