Best practice of Mixin and BaseEstimator inheritance order for proper MRO (Method Resolution Order)

[aoot]

I am confused what the best practice in which to inherit BaseEstimator vs various mixins.

In the example code here it states to list all the mixins BEFORE the BaseEstimator for proper MRO.

However, in the examples here, the mixins are listed AFTER BaseEstimator.

Thus my question is "which is the correct/better way to subclass?"

The documentation is wrong. Thanks for pointing out. Mixins should always be on the left.

Thanks, #28924 was a super quick turnaround!
