This document discusses the limitations of big data and predictive analytics in the legal field due to a lack of comprehensive data. Specifically, it notes that there is a scarcity of legal data compared to other industries due to smaller populations and less litigation. While data visualization can help understand large datasets, big data analytics in law requires careful consideration of bias, errors, and statistical significance. The document recommends using confidence intervals and inferential statistics when analyzing legal big data quantitatively. It also states that predictive analytics remain elusive for the legal profession due to data being siloed and not properly aggregated.
