Improved Risk Ratio Approximation by Complementary Log-Log Models: A Comparison with Logistic Models
Yuji Tsubota, Kenji Beppu
Odds ratios obtained from logistic models fail to approximate risk ratios with common outcomes, leading to potential misinterpretations about exposure effects by practitioners. Thi…
Efficient Multiple-Robust Estimation for Nonresponse Data Under Informative Sampling
Kosuke Morikawa, Kenji Beppu, Wataru Aida
Nonresponse after probability sampling is a universal challenge in survey sampling, often necessitating adjustments to mitigate sampling and selection bias simultaneously. This stu…
Verifiable identification condition for nonignorable nonresponse data with categorical instrumental variables
Kenji Beppu, Kosuke Morikawa
We consider a model identification problem in which an outcome variable contains nonignorable missing values. Statistical inference requires a guarantee of the model identifiabilit…
Identification enhanced generalised linear model estimation with nonignorable missing outcomes
Kenji Beppu, Jinung Choi, Kosuke Morikawa +1
Missing data often result in undesirable bias and loss of efficiency. These issues become substantial when the response mechanism is nonignorable, meaning that the response model d…
