A Two-Sample Test for Independence in 2×2 Contingency Tables with Both Margins Subject to Misclassification
两侧分类均有误差时 2×2 列联表独立性的双样本检验
A double sampling scheme is considered for estimation and testing under misclassification in both margins of a 2×2 contingency table; the matrix of misclassification probabilities is assumed to be unknown and nonsingular. Maximum likelihood estimators are given for the error-free and misclassification probabilities. Numerical methods are utilized to obtain maximum likelihood estimates under the independence hypothesis and the regularity conditions are affirmed for the…
