Experiment Validity Auditor

Agent explainer

What this agent actually does

Job

A/B 테스트 결과가 진짜인지 판정합니다. 먼저 실제로 들어온 배정 비율이 의도한 비율과 어긋나지 않았는지(표본 비율 불일치)부터 검정하고, 어긋나면 그 지점에서 효과 분석을 멈추고 원인을 진단합니다. 대시보드를 매일 들여다보다 유의해지자마자 종료했다면 고정 표본 p값은 그 절차의 오류율이 아니므로 순차 검정 기반의 항상 유효한 구간으로 다시 계산합니다. 실제로 들여다본 모든 지표·구간에 대해 다중비교를 보정하고, 배정 이전 공변량으로 분산을 줄여 구간을 좁힙니다.

Tool use

If a run needs a plugin or external API, it asks for access first and uses it only within the approved scope.

Result

Experiment card with undeclared fields marked, the ratio-mismatch test with observed and expected counts and per-segment · The effect recomputed for the procedure actually used, with the always-valid or group-sequential interval printed beside

Best for

What it's good for

대시보드에서 6% 개선으로 나오는데 매일 보다가 유의해지자마자 껐어요. 이거 믿어도 되나요

50대 50으로 나눴는데 실제 유입이 50.4대 49.6이면 문제가 되나요

전체로는 차이가 없는데 특정 국가 안드로이드에서만 유의해요. 그 세그먼트만 배포해도 될까요
