What is Predictive Analytics?
Predictive analytics is a branch of advanced analytics that uses historical data, statistical algorithms, and machine learning techniques to identify the likelihood of future outcomes based on historical data. The primary goal is to go beyond knowing what has happened to provide the best assessment of what will happen in the future.
Benefits of Predictive Analytics
- Enhanced Decision Making: Make informed decisions based on data-driven insights rather than gut feelings.
- Cost Savings: Optimize resources and reduce waste by predicting demand and managing inventory effectively.
- Risk Management: Identify potential risks and take preventive measures to mitigate them.
- Improved Customer Satisfaction: Anticipate customer needs and preferences, leading to better products and services.
Predictive Analytics Techniques
Predictive analytics techniques offer a wide range of applications powered by various types of models that generate valuable insights. To determine the best predictive analytics techniques for your organization, start with a clearly defined objective. Once you know the specific question you want to answer, you can select the most suitable model.
List of Predictive Analytics Models
- Regression Models: Used to predict continuous outcomes.
- Classification Models: These models categorize data into predefined classes.
- Clustering Models: Group similar data points together based on defined criteria.
- Time Series Models: Analyze data points collected or recorded at specific time intervals to forecast future values.
1. Regression Models in Predictive Analytics
Regression models estimate the relationship between variables, tracking how independent variables impact dependent variables to predict future outcomes. These models range from simple (one independent and one dependent variable) to multiple linear regression (multiple independent variables). Various regression techniques can be applied based on the specific use case.
By defining variable relationships, organizations can conduct scenario or 'what-if' analysis, testing how changes in independent variables affect outcomes.
Application of Regression Models
For example, a company might use a regression model to analyze how product qualities influence purchase likelihood, such as identifying a correlation between blue shirts and higher sales. These insights help refine marketing strategies and product development, optimizing future performance.
2. Classification Models in Predictive Analytics
Classification models categorize data based on historical knowledge. Using a labeled training dataset, the classification algorithm learns correlations between data and labels and then categorizes new data. Popular techniques include decision trees, random forests, and text analytics.
These models are highly adaptable and can be retrained with new data, making them useful across various industries.
Application of Classification Models
For example, banks use classification models to detect fraudulent transactions. By analyzing millions of past transactions, the algorithm identifies patterns indicative of fraud and alerts customers to suspicious activity.
3. Clustering Models in Predictive Analytics
Clustering models group data based on similar attributes. Using a data matrix that associates items with relevant features, the algorithm clusters items with shared features, uncovering hidden patterns. Organizations use clustering models to group customers for personalized targeting strategies.
Application of Clustering Models
A restaurant might cluster customers by location and mail flyers only to those within a certain driving distance of a new location.
4. Time-series Models in Predictive Analytics
Time series models analyze data points in relation to time, making time one of the most common variables in predictive analytics. These models use historical data to predict future metrics. For example, analyzing data from the past year can help forecast the upcoming weeks.
Time series analyses are versatile, used for applications like seasonality analysis (predicting how assets are affected by certain times of the year) and trend analysis (determining asset movements over time).
Application of Time-series Models
Forecasting sales for the next quarter, predicting store visitor numbers, or even determining peak flu seasons.

Customize View Data: This feature is available on Tableau Server, Desktop and Tableau Online
This feature enables to reshape the tabular data behind your visualisation in the View data interface. One can create new columns, remove columns from the default view, change the order and sort the data using this feature. This reshaped data can also be exported as csv file to be shared with the team.
Change the root table: This feature is available on Tableau Server, Desktop and Tableau Online
Managing multiple data tables becomes easier and flexible with this new feature. One can swap any table to be the root table with a single click. This allows one to change the layout of the table quickly, reshape the data with a different root table and delete a specific table without deleting child nodes. For e.g., let us assume a user had to create a data source for an analysis using 3 tables namely ‘customers’, ‘orders’ and ‘returns’. The user creates the data model such that ‘customers’ is the root table followed by ‘orders’ and ‘returns’. But after performing some analysis the user realises that ‘orders’ should be the main root table. In such cases the user would have to re-create the data again from scratch but with the new ‘Swap with root table’ feature user can do the changes with a few clicks.
