%description
Balancing computational and statistical efficiency, subsampling techniques
offer a practical solution for handling large-scale data analysis.
Subsampling methods enhance statistical modeling for massive datasets by
efficiently drawing representative subsamples from full dataset based on
tailored sampling probabilities. These probabilities are optimized for
specific goals, such as minimizing the variance of coefficient estimates
or reducing prediction error.
