%description
Distributed Online Mean Tests is a powerful tool designed to efficiently
process and analyze distributed datasets. It enables users to perform mean
tests in an online, distributed manner, making it highly suitable for
large-scale data analysis. By leveraging advanced computational
techniques, 'Domean' ensures robust and scalable solutions for statistical
analysis, particularly in scenarios where data is dispersed across
multiple nodes or sources. This package is ideal for researchers and
practitioners working with high-dimensional data, providing a flexible and
efficient framework for mean testing. The philosophy of 'Domean' is
described in Guo G.(2025) <doi:10.1016/j.physa.2024.130308>.
