Predictions
Part of the Municipalities lab
A regression learns the relationship between the demographic indicators and the average income of the region's municipalities, then **estimates** it for each one: where the estimate misses the most, something the demographic data alone can't explain is going on. The **R²** in the status tells you how much of the income the model explains.

How it works
This is a Reactive app: a plain text document that your browser turns into a working app — forms, live data, tables, statistics and even charts, with nothing to install or configure.
- Use it right away. Hit “Use this app”: it opens right in your browser, ready to go, with data saved only on your device.
- Your data stays yours. Everything is stored locally on your device, kept separate for each app: no account, no server, nothing to set up.
- Make it your own. The text below is the entire app: copy it, tweak fields, views and words, and your changes become interactive instantly.
- Share it as a file. An app is a simple file: save it, export it or share it with a link; and with encrypted collaboration several people edit the same data in real time.

## How much income do age and foreigners "explain"?
A regression learns the relationship between the demographic indicators and
the average income of the region's municipalities, then **estimates** it for
each one: where the estimate misses the most, something the demographic data
alone can't explain is going on. The **R²** in the status tells you how much
of the income the model explains.

Each point is a municipality: the horizontal axis is the **real** income, the
vertical one the model's **estimate**. The closer the points sit to the
diagonal, the better the model explains.
