Distance metrics help quantify how similar or different data points or sets are. This image shows visual examples of nine popular ones used across data science and machine learning.

It covers Euclidean, cosine, Hamming, Manhattan, Minkowski, Chebyshev, Jaccard, Haversine, and Sørensen-Dice, each with a simple diagram of how the calculation works.

These metrics sit at the core of clustering algorithms, nearest-neighbor methods, recommendation systems, natural language processing tasks, and geospatial analysis.

If you want to explore your data visually without spending hours coding, the Jamovi GUI is a game-changer. It offers seamless integration with R, allowing you to combine a simple point-and-click interface with the flexibility of advanced scripting. This makes it easy to spot patterns, understand relationships, and communicate results with clear, customizable plots, all in one tool.

Why use the Jamovi GUI?

✔️ No heavy coding required, work visually
✔️ Easily set your target variable, predictor variables, and panels
✔️ Customize plots with confidence bands, ghost lines, and transparency options
✔️ See trends and differences at a glance
✔️ Works well for both simple and multi-variable analysis
✔️ Seamless integration with R for custom scripting and advanced analysis

The image below shows the Jamovi GUI in action. You can see examples of scatterplots with fitted lines, density plots, faceted scatterplots, and violin plots, all created with just a few clicks. The interface makes it easy to select variables, adjust settings, and generate publication-ready plots instantly. Images shown here are taken from: https://t.co/4fymjvakcS

To those who are still determined to make everything AI-resistant!

But the tl;dr version is that the model proved a result that in my assessment would have made a perfectly reasonable chapter in a PhD thesis. It did this in a total of a couple of hours, with a few prompts from me that contained no mathematical input whatsoever.

@SamiraKorani من حسرت بحث‌های قبل از انتخابات هلند رو می‌خورم. بحث‌ها کاملا روی زمین بر اساس عدد و رقم دقیق. به خصوص در مورد هزینه‌ها و درآمد ها و بودجه و ... «همه» بحث‌های سیاسی و اقتصاد سیاسی ایران «داخل» و «خارج» از حکومت همه دقیقا «روی هوا» و بر مبنای «آرزوها»!

@YujungHwang3 And think of those people who still prefer RStudio over Positron!

Taking longer than usual. Trying again shortly (attempt .. of 10)

It seems @claudeai is not working with my Max subscription.

@AnthropicAI

[Mahdi Rahimi @GeoMahdi]

So, it seems I am paying for @claudeai's max subscription to keep getting "Conversation not found" all the time!
