A Comparison of Parameter Estimation Methods for Shared Frailty Models
Tingxuan Wu, Cindy Feng, Longhai Li
This paper compares six different parameter estimation methods for shared frailty models via a series of simulation studies. A shared frailty model is a survival model that incorpo…
Cross-validatory Z-Residual for Diagnosing Shared Frailty Models
Tingxuan Wu, Cindy Feng, Longhai Li
Residual diagnostic methods play a critical role in assessing model assumptions and detecting outliers in statistical modelling. In the context of survival models with censored obs…
Z-residual diagnostics for detecting misspecification of the functional form of covariates for shared frailty models
Tingxuan Wu, Longhai Li, Cindy Feng
In survival analysis, the hazard function often depends on a set of covariates. Martingale and deviance residual are most widely used for examining the validity of the function for…
Model diagnostics for censored regression via randomized survival probabilities
Longhai Li, Tingxuan Wu, Cindy Feng
Residuals in normal regression are used to assess a model's goodness-of-fit (GOF) and discover directions for improving the model. However, there is a lack of residuals with a char…
