Show Suggested Answer

Suggested Answer: B

Performance testing is a type of testing that should be performed at the production level before deploying a newly retrained model. Performance testing measures how well the model meets the non-functional requirements, such as speed, scalability, reliability, availability, and resource consumption. Performance testing can help identify any bottlenecks or issues that may affect the user experience or satisfaction with the model.

Wait, so the Beta value is the type II error rate, not the type I error rate? I always get those two mixed up. Good thing this is a multiple-choice exam and not an open-ended question!

Alright, let's see... The Beta value is the type II error rate, and the statistical power is the inverse of that. Seems pretty straightforward to me. I'll go with C) and A).

I agree, the Beta value is indeed the rate of type II errors for the test.

Haha, D) is clearly a trick question. The Beta in an Alpha/Beta test? That's not even a thing! I'm going with C) and one of the other correct answers.

Hmm, I'm a bit confused here. Isn't the Beta value related to the two variants in an A/B test? I'll have to think this one through a bit more.

C) is definitely correct - the statistical power is 1 - Beta. I remember that from my statistics class. The Beta is the type II error rate, not the type I error rate. This is a pretty straightforward question.
