Thanks for adding a label. We are encouraging people to use them because it was a stated goal when the magazine was solicited for input on community guidelines and rules, but we won't be like, coming in behind anyone to fact check whether the correct label was applied.
However, you may find this short glossary helpful:
Glossary of terms: Editorials have author bylines that denote a collection of people within a
news organization, such as candidate endorsements from a newspaper’s staff. Opinions have
author bylines from a single (maybe two) writer(s). Analysis is when an author starts with
factually verified current events and reports then explains deeper significance or motivation,
predicts future outcomes, or makes a policy recommendation based on the starting data.
