Cohort analysis explained: purpose, types, and how to use

This post explains cohort analysis, its purpose, and types (time-based, behavior-based, size-based, event-based). It details how to perform cohort analysis using SQL and Python libraries (Pandas, Polars) and R packages, highlighting Hex as a platform that combines these tools. A practical example of building event-based cohort tables from raw 'users' and 'events' data is provided, focusing on defining cohorts based on the first sign-up month.
