Ever wondered how to group your customers, products, or markets in a way that actually reveals meaningful patterns — without deciding upfront how many groups you need?

That's exactly what agglomerative hierarchical clustering does, and our latest guide breaks it all down in plain language.

Agglomerative hierarchical clustering is one of the most intuitive and powerful techniques in data analysis. It works by starting with each data point as its own cluster, then progressively merging the closest ones together — step by step — until a clear structure emerges. The result is a visual tree (called a dendrogram) that lets you explore your data at multiple levels of granularity.

For SMEs, this matters more than you might think.

Imagine being able to segment your customer base without guessing how many segments exist. Or grouping your product catalogue by purchasing behaviour patterns. Or identifying which regional markets behave similarly — all from your existing data.

Our 2026 comprehensive guide covers:

- How the algorithm works, step by step
- The different linkage methods and when to use each
- Practical examples with Python code
- How to interpret and apply the results to real business decisions

You don't need a data science team to benefit from this. With the right tools and a clear understanding of the method, these techniques are well within reach for any analytically curious business owner or manager.

We've written this guide specifically to bridge the gap between technical depth and practical business application.

Have you ever used clustering in your business analysis — or is it something you've been curious about but haven't tried yet?

If you're a landlord or managing commercial property leases in Europe, getting the ISTAT rent indexation calculation wrong can be a costly mistake — and it's more common than you'd think.

We've just updated our practical guide on ISTAT rent indexing for 2026, and it covers everything you need to know to get this right without the headaches.

Here's why this matters: rent indexation tied to the FOI (Families of Workers and Employees) index is a legal requirement for many Italian rental contracts. But the calculation isn't always straightforward — especially when indices are revised, reference periods shift, or you're working with partial-year adjustments.

Our updated guide breaks down:

- How the ISTAT FOI index actually works and where to find the official figures
- Step-by-step calculation methodology for 2026
- The most common errors landlords and property managers make (and how to avoid them)
- What's changed compared to previous years

Whether you manage a handful of residential properties or a portfolio of commercial leases, having a clear, reliable calculation process protects you from disputes and ensures you're applying the correct adjustment — nothing more, nothing less.

This is exactly the kind of practical, regulation-specific knowledge that ELECTE is built to support: turning complex data and compliance requirements into clear, actionable guidance for businesses and professionals across Europe.

The full guide is available now — check the link to read it.
