Semiparametric Regression for Misclassified Competing Risks Data

Theofanis Balanos, Constantin T. Yiannoutsos, Felix M. Pabon-Rodriguez +2

The analysis of competing risks data is often complicated by misclassification of the cause of failure. This issue can lead to seriously biased estimates and invalid conclusions. O…

Robustness intervals for competing risks analysis with causes of failure missing not at random

Giorgos Bakoyannis, Aristofanis Rontogiannis, Ying Zhang +3

Analysis of competing risks data is often complicated by the incomplete or selectively missing information on the cause of failure. Standard approaches typically assume that the ca…

Marginal Regression on Transient State Occupation Probabilities with Clustered Multistate Process Data

Wenxian Zhou, Giorgos Bakoyannis, Ying Zhang +1

Clustered multistate process data are commonly encountered in multicenter observational studies and clinical trials. A clinically important estimand with such data is the marginal…

Variance estimation in pseudo-expected estimating equations for missing data

Giorgos Bakoyannis, Philani B. Mpofu, Andrea Broyles +1

Missing data is a common challenge in biomedical research. This fact, along with growing dataset volumes of the modern era, make the issue of computationally-efficient analysis wit…

Semiparametric Marginal Regression for Clustered Competing Risks Data with Missing Cause of Failure

Wenxian Zhou, Giorgos Bakoyannis, Ying Zhang +1

Clustered competing risks data are commonly encountered in multicenter studies. The analysis of such data is often complicated due to informative cluster size, a situation where th…

Nonparametric analysis of nonhomogeneous multi-state processes based on clustered observations

Giorgos Bakoyannis

Frequently, clinical trials and observational studies involve complex event history data with multiple events. When the observations are independent, the analysis of such studies c…

Semiparametric regression and risk prediction with competing risks data under missing cause of failure

Giorgos Bakoyannis, Ying Zhang, Constantin T. Yiannoutsos

The cause of failure in cohort studies that involve competing risks is frequently incompletely observed. To address this, several methods have been proposed for the semiparametric…
