👉 Publishing math, often referred to as "pub math," is a set of statistical methods and formulas used to analyze and interpret data in the context of publishing. It helps publishers understand and predict various metrics such as word count, page views, and reader engagement, enabling them to make informed decisions about book production, marketing strategies, and author contracts. Key concepts include the DeLong formula for estimating future sales based on historical data, the Herfindahl-Hirschman Index (HHI) to assess market concentration and competition, and the use of regression analysis to identify factors influencing book performance. By applying these mathematical techniques, publishers can optimize their operations and better align with reader preferences and market trends.
