Study Notes
Diagnostic Analytics
- Answers "Why did it happen?" by identifying causes of past events.
- Helps organizations understand relationships between different variables.
- Key techniques include Data Discovery, Data Mining, and Correlations.
- Advanced methods like Regression and Time Series Analysis are often used.
- Machine Learning Models assist in uncovering complex patterns from large datasets.
Predictive Analytics
- Focuses on future possibilities and outcomes, answering "What could happen?"
- Utilizes historical data through statistical algorithms and machine learning.
- Applications include sales forecasting, credit scoring, and predicting customer behavior.
- Emphasizes proactive decision-making based on potential future scenarios.
- Commonly implemented using programming languages like Python or R.
Prescriptive Analytics
- Recommends specific actions to achieve desired outcomes (e.g., optimizing supply chains).
- Combines insights from Descriptive and Predictive analytics to guide decisions.
