Hey guys! Can you tell me about your A/B testing mechanisms? How it count? Didn't find in the documentation

I'm not sure exactly what you mean. Are you talking about "count" metrics like pages per visit?

No, I'm talking about math part.

We have some docs on our statistics methodology plus a link to a stats white paper if that helps. https://docs.growthbook.io/statistics

Thank you Jeremy. After some time I guess I'll return with specific questions)
