I built a U.S. Housing Affordability Index in Python using Census and FRED data to compare income, home values, mortgage rates, and regional affordability.
The analysis shows a clear divide.
Some Midwest markets still offer much stronger affordability, while many Western states remain under heavy pressure from high home values and borrowing costs.
The article covers:
📊 A complete housing affordability index
🐍 Python code you can reuse
🗺️ U.S. state and regional comparisons
💰 Mortgage rate sensitivity analysis
📈 Interactive and animated charts
🏡 Key economic factors shaping affordability
🔍 Census and FRED data sources
If you work in data analysis, economics, real estate, research, or Python, this is a practical project worth exploring.

I tested the idea in Python using real FRED data and two popular Treasury spreads:
📊 10 Year minus 2 Year Treasury Spread
📊 10 Year minus 3 Month Treasury Spread
📉 US recession data from FRED
In the full analysis, I break down:
✅ How to download and clean FRED data in Python
✅ How to detect yield curve inversions
✅ How often inversion signals appeared before recessions
✅ True signals vs false signals
✅ Precision, recall, and recession lead time
✅ How persistence changes the results
✅ Interactive charts and a complete Python backtest
One key lesson stood out.
The yield curve can be a useful early warning signal, but it should not be treated as a perfect recession clock.
If you work with economics, finance, investing, data science, or Python, this tutorial gives you a practical way to test the indicator yourself instead of simply trusting the common claim.

I just published a practical tutorial on GDP Forecasting in Python Using U.S. Economic Data, built with official BEA and FRED data.
Instead of jumping straight into a complex model, the analysis starts with the basics and tests whether each model actually improves the forecast.
Inside the tutorial, I cover:
🐍 GDP forecasting with Python
📊 Real GDP data from BEA and FRED
⏳ Time ordered train and test periods
📈 Quarterly GDP growth calculations
🔁 Rolling origin forecast evaluation
🧠 AutoReg and Ridge regression models
📉 MAE and RMSE model comparison
⚠️ Data leakage and revision bias
📅 ALFRED vintage data considerations
🎯 A one quarter ahead GDP forecast
▶️ An interactive forecast animation
One important finding from the model test:
The four lag AutoReg model performed best during the recent evaluation period, with about 1.24 percentage points MAE and 1.57 RMSE.
The tutorial model then produced a 2026 Q3 real GDP growth forecast of about 3.0 percent annualized.
But the bigger lesson is not the forecast number.
A good forecasting workflow should always ask:
Did the model beat a simple benchmark?
Was future information accidentally used?
Were forecasts tested on data the model had never seen?
How much uncertainty is around the prediction?
If you work with Python, economics, forecasting, data science, macroeconomic research, or financial analysis, this tutorial gives you a complete workflow you can build on.

Most researchers are using the wrong normality test.
If you're automatically running the 𝐊𝐨𝐥𝐦𝐨𝐠𝐨𝐫𝐨𝐯-𝐒𝐦𝐢𝐫𝐧𝐨𝐯 (𝐊𝐒) test because it's the default in your software, you could be making a statistical mistake that affects your results.
In this new guide, I explain:
📊 Why the 𝗦𝗵𝗮𝗽𝗶𝗿𝗼-𝗪𝗶𝗹𝗸 𝘁𝗲𝘀𝘁 is usually the better choice
📈 When the KS test is actually appropriate
⚠️ The hidden Lilliefors correction issue that many researchers miss
🧠 Why a significant normality test doesn't always mean your analysis is invalid
🤖 How AI-assisted statistical software is changing assumption checking in 2026
Whether you're working in SPSS, R, Python, SAS, Stata, Jamovi, or JASP, this article offers practical guidance, real-world examples, and evidence-based recommendations you can apply immediately.
If you analyze data for a thesis, journal paper, clinical study, or business project, this comparison could help you avoid one of the most common statistical errors.

AI data centers are getting hotter, but NVIDIA’s answer is not colder air.
The company says its new Rubin generation AI systems can use liquid coolant entering the rack at up to 45°C. That may sound risky, but warmer coolant can make cooling more efficient, reduce the need for chillers, lower water use, cut noise, and allow more computing power in less space.
The biggest shift is simple. Instead of relying on fans and cold aisles, heat is captured directly from chips and moved through a closed liquid loop.
Still, the benefits depend on climate, facility design, operating costs, and local infrastructure.
We explored how this technology works, where it can help, and what challenges data center operators may face.
