Economists at The Brattle Group routinely host, develop, and work with large-scale datasets that transform detailed customer, supplier, transaction, and other types of so-called “big data” into information that is useful for economic analysis. Our specialized data services ensure that scale does not prevent us from revealing the essential economic stories the data can tell.

Economic and financial analysis based upon large-scale datasets is a core requirement in complex litigation. Brattle has the infrastructure and expertise that enables us to get these datasets up and running on high performance big-data platforms. We provide data services for clients, testifying experts, courts, and regulators in connection with litigation matters and complex commercial disputes. The breadth and depth of our experience enables us to offer exceptional data processing and analytics capabilities.

Big data may exceed or strain the memory and hard disk capacity of traditional computing platforms, requiring more advanced techniques for storing, manipulating, visualizing, and summarizing such large datasets. Even if the data can fit within the capacity limits of a traditional computing platform, the processing time needed to perform analysis may limit the scope of feasible analysis and the productivity of experts. Using a specialized big data platform, such as a Hadoop cluster, makes complex analysis of large datasets feasible, timely, and more efficient.

We have experience deploying our own Hadoop clusters and other terabyte-scale data storage solutions, and working with third party hosting companies to provide secure remote access. The programming languages we most commonly use in conjunction with the Hadoop platform are Python, R, SQL, and Pig. We use these languages to transform, extract, and sample low-level transactional data to produce datasets more suitable for traditional analysis tools such as Excel or Stata. Our expertise and experience in deploying Hadoop clusters provides Brattle with a competitive advantage in extracting from raw data the economic insights of critical importance to each case.
