The attribution

Whether the change caused the movement.

The part

What it is

Other things changed too. Where possible the change should be made in one segment or region first, which makes attribution straightforward.

Where that is impossible, the confounders should be named rather than ignored.

The smallest level

The attributes it carries

Each attribute is one of the framework’s shared types. What a date is, and how it is written, is defined once for the whole model — the note here says what it means in this particular place.
