  "Description": "Statistical hypothesis testing using the Delta method as\nproposed by Deng et al. (2018) <doi:10.1145/3219819.3219919>.\nThis method replaces the standard variance estimation formula\nin the Z-test with an approximate formula derived via the Delta\nmethod, which can account for within-user correlation.",
