This document discusses predictive analysis and the challenges, statistics, assumptions, and relevance to managers. It introduces the author and defines predictive analysis as using past data and statistical methods to predict the future. The main challenges are lack of good data and unique identifiers. Regression analysis is commonly used to correlate attributes and predict likelihoods. The key assumption is that the future will be like the past, but this can be invalidated over time if assumptions become irrelevant. Predictive analytics allows managers to proactively address opportunities and losses.
