What is Diagnostic Analytics?
Diagnostic analytics is a critical component of the 4 types of data analysis, which also include descriptive analytics, predictive analytics, and prescriptive analytics. It specifically focuses on investigating past performance to understand the reasons behind outcomes. By examining data more deeply, diagnostic analytics identifies patterns, anomalies, and correlations, offering insights into why certain events occurred. This analytical approach empowers organizations to make more informed decisions by understanding the root causes of their data trends.
How can diagnostic analytics help in the real world? In a healthcare setting, diagnostic analytics would explore the data and make correlations. For instance, it may help you determine that many patients’ symptoms—high fever, dry cough, and fatigue—point to the same infectious agent. You now have an explanation for the sudden spike in volume at the ER.Often, diagnostic analysis is referred to as root cause analysis. It involves processes such as data discovery, data mining, and drill down and drill through.
Key Components of Diagnostic Analytics
- Data Mining: The process of exploring large datasets to find patterns.
- Root Cause Analysis: Identifying the fundamental cause of a problem.
- Correlation Analysis: Examining the relationship between different data points.
How Diagnostic Analytics Works
Diagnostic analytics uses statistical techniques and models to identify anomalies, patterns, and trends in historical data, helping businesses understand why something happened.
The Process of Diagnostic Analytics
- Data Collection: Gathering relevant data from various sources.
- Data Processing: Cleaning and preparing data for analysis.
