📊 Understanding the Concept

In traditional regression, we assume that coefficients are constant over time. But in real-world scenarios – such as stock prices, temperature changes, or patient health indicators – relationships often evolve slowly over time. 🌍 This is where slowly varying regression comes into play. It allows coefficients to drift or adapt gently over the sample, making models more aligned with natural and economic phenomena.

When coupled with sparsity – meaning that only a few predictors significantly influence the outcome – we get a model that is both adaptive and parsimonious. 🧮

🔬 Why Sparsity Matters

Imagine trying to predict the future of stock prices using thousands of potential features – daily news sentiment, currency shifts, interest rates, global events, and more. Most of these features may have no real impact! Sparsity helps us identify only the relevant variables, reducing overfitting and improving prediction. 🧩

Combined with slow variation, the model learns not just what matters, but when it matters – and how the influence changes over time.

⚙️ Technical Framework

The core idea relies on penalized regression techniques like Lasso or Fused Lasso, extended to capture temporal or spatial smoothness. 📘 The model penalizes both:

  • The size of coefficients (to enforce sparsity)

  • The differences between neighboring coefficients (to enforce smooth variation)

This dual penalty ensures that the model selects a few meaningful predictors and allows their effects to vary slowly across time points or spatial locations.
