I am learning about the way ES uses regression analysis and looking at the example of flight carriers, I wonder if it is possible to group on a certain field such as carrier and have predictions per carrier.

In the example, I would then be able to ask for a prediction for 'ES-Air' only.

Is that possible? If so what would need to be done on creating the regression model and how does the query looks like?

(update, adding link to example: [https://www.elastic.co/guide/en/machine-learning/7.5/flightdata-regression.html](https://www.elastic.co/guide/en/machine-learning/7.5/flightdata-regression.html) )

thnx

Sven
