Lesson 2 of 10 · AI for Financial Forecasting Support

In this lesson. Calendar, currency, and restatements in a dictionary.

What you will learn

  • Calendar
  • Currency
  • Restatements

Walkthrough

You will document the series. AI that “analyzes” an undocumented export will hallucinate seasonality. The dictionary is the work.

Work through the ideas in order. After each point, pause and connect it to a task you already do — a document, a workflow, or a feature you own. The goal of AI for Financial Forecasting Support is usable skill, not a pile of notes.

If something is unclear, rewrite it in your own words before you continue. Teaching the step back to yourself is the fastest way to see gaps.

Practice

Write a dictionary for one series.

Keep the first attempt small. A finished example you can reuse beats a perfect plan you never run.

Check your understanding
