General

Cohort Analysis

Cohort analysis is a method of analyzing metrics across different groups (i.e., cohorts), which share common characteristics on the accumulated data.

These characteristics play a critical role in user profiling and the decision-making process in data-driven organizations.

Healthcare

Drug Effect Analysis

A usage of cohort analysis in healthcare analytics can be side-effect evaluation of a tested drug in clinical trials, where the clinicians need to distinguish the effectiveness of new medicines (e.g., Medicine A) on a certain feature (e.g., Labtest A) among different patient groups.

Finance

Retention Analysis

A usage of cohort analysis in finance analytics can be retention analysis that is to analyze users' actions to understand how and when customers churn.

Analyzing the retention rate is critical to learning how to maintain profitable customers and new user acquisition rates.
