“Results: We find that the 12th-order polynomial fit to the spectral passband utilised in the published study leads to spurious results. Following their recipe, five other >10 sigma lines can be produced in absorption or emission within 60 km/s from the PH3 1-0 transition frequency by suppressing the surrounding noise. Our independent analysis shows a feature near the PH3 frequency at a ~2 sigma level, below the common threshold for statistical significance. Since the spectral data have a non-Gaussian distribution, we consider a feature at such level as statistically unreliable that cannot be linked to a false positive probability.
Conclusions: We find that the published 267-GHz ALMA data provide no statistical evidence for phosphine in the atmosphere of Venus.”

【🔥閱讀時間:5-10分鐘 - 你該了解的4大A/B Test 因素🔥】
A/B test 操作過程中,有四項因素需要注意:
🔹確保改變與結果之間真的有因果關係
🔹最小可檢測效應(Minimum Detectable Effect -MDE)
🔹檢定力(Power)
🔹顯著性差異(Statistical Significance)
許多人對於A/B Test 在數據、假設與結果判斷上有迷思
導致驗證結果有誤,效果不如預期
文章中提到「假設必須要有意義」才不會浪費A/B Test 測試過程
不斷的測試與學習是A/B Test 的核心精神!
