  • On needles and haysacks: New way to deal with large datasets

    The ability to gather vast amounts of data and create huge datasets has created a problem: Data has outgrown data analysis; for more than eighty years one of the most common methods of statistical prediction has been maximum likelihood estimation (MLE); Brown University researchers offer a better way to deal with the enormous statistical uncertainty created by large datasets
