Hierarchical Cluster Analysis
Analyze any type of data with Sourcetable. Talk to Sourcetable's AI chatbot to tell it what analysis you want to run, and watch Sourcetable do the rest.
Introduction
Hierarchical Cluster Analysis (HCA) groups similar data points into clusters through an iterative process. Starting with each data point as its own cluster, the analysis combines the closest clusters until reaching a specified stopping point. In Excel, HCA requires the XLSTAT add-in, which uses Euclidean distance and Ward's method by default. The analysis typically creates 2-5 clusters, with options like the Hartigan index helping determine the optimal number.
Sourcetable provides a simpler alternative through its AI-powered spreadsheet platform. Rather than navigating complex Excel functions, users can upload data files or connect databases and simply tell Sourcetable's AI chatbot what analysis they need. The AI understands natural language requests and automatically handles all calculations and visualizations.

Benefits of Hierarchical Cluster Analysis with Sourcetable
Hierarchical cluster analysis offers a straightforward approach to data clustering. The method creates clear, tree-like dendrograms that represent data relationships, making it easy to understand and implement.
Types and Capabilities
Hierarchical clustering provides two distinct approaches: agglomerative (bottom-up) and divisive (top-down). Agglomerative clustering excels at identifying small clusters, while divisive clustering effectively identifies large clusters.
Advantages of Using Sourcetable
Sourcetable's AI-powered platform revolutionizes hierarchical cluster analysis by allowing users to perform complex analyses through natural language commands. Instead of manually programming functions, users can simply tell Sourcetable what they want to analyze, and the AI handles the technical implementation.
Unlike Excel's traditional approach, Sourcetable simplifies the entire process through its AI chatbot interface. Users can upload data files of any size or connect databases, then direct the AI to perform cluster analysis, create visualizations, and generate insights - all without needing to know specific functions or formulas.
Statistical Implementation
Sourcetable implements various agglomerative methods for measuring cluster dissimilarity, including maximum linkage, minimum linkage, mean linkage, centroid linkage, and Ward's minimum variance method. These methods can be applied using functions like hclust, agnes, and diana for divisive analysis.
Types of Hierarchical Cluster Analysis in Sourcetable
Hierarchical clustering in Sourcetable's AI-powered platform simplifies complex analysis through natural language commands. Simply upload your data or connect your database, then ask Sourcetable's AI to perform either agglomerative or divisive clustering, which create tree-like structures called dendrograms.
Agglomerative Clustering
Tell Sourcetable's AI to perform agglomerative (bottom-up) clustering for identifying small clusters in your data. The AI handles all computational aspects, including dissimilarity measurements and linkage method selection (complete, average, single, or Ward's minimum variance).
Divisive Clustering
For identifying large clusters, instruct Sourcetable's AI to conduct divisive (top-down) clustering. The AI manages the hierarchical breakdown of your data, creating comprehensive cluster structures without requiring manual function calls.
Cluster Identification
Sourcetable's AI can automatically identify and extract sub-groups from dendrograms based on your specifications. The platform handles data standardization and distance measurements internally, delivering clear cluster visualizations through its conversational interface.

Frequently Asked Questions
What is Hierarchical Cluster Analysis and what are its main outputs?
Hierarchical Cluster Analysis is an algorithm that groups similar objects into distinct clusters, where objects within each cluster are broadly similar to each other. It starts by treating each observation as a separate cluster and iteratively identifies and merges the closest clusters. The main output is a dendrogram, which shows the hierarchical relationship between the clusters.
What are the main applications of Hierarchical Cluster Analysis?
Hierarchical Cluster Analysis has applications across multiple fields: in biology for phylogenetic analysis and gene expression studies, in marketing for customer segmentation based on purchasing behavior, in social science for grouping individuals based on survey responses, and in image processing for image segmentation and object recognition.
How can you perform Hierarchical Cluster Analysis in Sourcetable?
You can perform Hierarchical Cluster Analysis in Sourcetable by simply uploading your data file or connecting your database, then using natural language to tell Sourcetable's AI chatbot what analysis you want to perform. The AI will automatically handle the technical details, including choosing between agglomerative (bottom-up) or divisive (top-down) clustering methods, and create appropriate visualizations like heatmaps and dendrograms to represent your results.
Conclusion
Traditional Hierarchical Cluster Analysis in Excel requires XLSTAT software, proper data formatting in rates per 1000 inhabitants, and familiarity with methods like Euclidean distance and Ward's method. The process involves determining cluster numbers between 2 and 5 using indices like Hartigan, and potentially employing k-means for more homogeneous clusters.
For a more streamlined approach, Sourcetable offers an AI-powered spreadsheet that lets you perform analyses through natural conversation. Simply upload your data and tell Sourcetable's AI chatbot what analysis you want to perform. The AI handles all the technical details, making complex analyses like hierarchical clustering accessible without any Excel expertise.
