Tableau invests in advanced analytics so that you can get to the root of your questions, no matter how complex they become. We’ve revamped our whitepaper, Advanced Analytics with Tableau, with information about our evolving feature set, and in it we explore how Tableau addresses all stages of an analytics project by drawing on key, built-in advanced capabilities.
In this post, we’ll talk about Tableau’s approach to the scenarios analysts and data scientists work with every day, and provide you with resources to conduct sophisticated data analysis.
Segmentation and cohort analysis
Tableau promotes an investigative flow for rapid and flexible cohort analysis. Move through different perspectives quickly by slicing and dicing the data along as many dimensions as you want. Automated clustering—a machine learning technique—also helps improve your segments. This is often useful for spotting difficult-to-see patterns in data sets with high dimensionality.
Automatically segment your data using clustering.
By letting you quickly segment and categorize data, Tableau enables you to perform powerful cohort analysis with relative ease. These capabilities also help data scientists investigate initial hypotheses and test scenarios.

Scenario and what-if analysis
By combining Tableau’s flexible front-end with powerful input capabilities, you can quickly modify calculations and test different scenarios. With sets, groups, drag-and-drop segmentation, and parameters, Tableau makes it possible to move from theories and questions to a professional-looking dashboard that allows even non-experts to ask questions and test their own scenarios.
With this parameter-driven sales report, you can explore the effect of quotas, commissions, and salaries within the organization.
Streamlining what-if analysis empowers you to focus on the more complex aspects of your analysis and deliver greater insights. At the same time, it’s easy to create intuitive visuals that help anyone engage with data.

Sophisticated calculations and statistical functions
Tableau possesses a robust calculation language, making it easy to augment your analysis with arbitrary calculations and perform complex data manipulations with concise expressions. In conjunction with the summary card feature, Tableau gives you built-in options—from nesting basic aggregations to statistical calculations like standard deviation, mode, kurtosis, skewness, correlation, and covariance.
An LOD expression is used to calculate the running sum of total sales by first quarter of purchase date.
With Table Calculations, challenging database work—such as manipulating aggregated data, creating complex lags, and building data structure-dependent aggregations—requires just a few clicks or a simple expression. This both empowers non-technical users and saves experts countless hours and laborious SQL code.

Time-series and predictive analysis
Tableau natively supports rich time-series analysis, meaning you can explore seasonality, trends, sample your data, run predictive analyses like forecasting, and perform other common time-series operations within a robust UI.
Forecasting automatically predicts sales by region.
Easy predictive analytics adds tremendous value to almost any data project. By supporting both complex configuration and simple interactive modeling, Tableau serves both the data scientist and the end user.

External services integration
R and Python plugins provide the power and ease of use of Tableau’s front-end, while allowing you to leverage prior statistical work in other platforms and handle nuanced machine learning workflows.
R and Tableau were used to calculate and visualize the results of significance testing.
The combination of Tableau with Python and R allows you to express the results of complex modeling as beautiful and engaging visuals for consumption. People of all skill levels can ask what-if questions and evaluate hypothetical scenarios by interacting with controls embedded into the dashboards.

In many ways, Tableau stands alone among analytics platforms: We design Tableau with both the business user and the data scientist in mind. By staying focused on our mission to empower people to ask interesting questions of their data as quickly as possible, the Tableau platform delivers valuable functionality for everyone.
