Confidence Intervals for the Risk Difference in Combined Unilateral and Bilateral Data Incorporating a Distribution-Based Approach
Jia Zhou, Chang-Xing Ma
Combined unilateral and bilateral binary outcomes frequently arise in studies involving paired organs. The risk difference is a clinically interpretable measure for comparing treat…
Testing Risk Difference of Two Proportions for Combined Unilateral and Bilateral Data
Jia Zhou, Chang-Xing Ma
In clinical studies with paired organs, binary outcomes often exhibit intra-subject correlation and may include a mixture of unilateral and bilateral observations. Under Donner's c…
Homogeneity Test of Proportions for Combined Unilateral and Bilateral Data via GEE and MLE Approaches
Jia Zhou, Chang-Xing Ma
In clinical trials involving paired organs such as eyes, ears, and kidneys, binary outcomes may be collected bilaterally or unilaterally. In such combined datasets, bilateral outco…
Goodness-of-fit Tests for Combined Unilateral and Bilateral Data
Jia Zhou, Chang-Xing Ma
Clinical trials involving paired organs often yield a mixture of unilateral and bilateral data, where each subject may contribute either one or two responses under certain circumst…
