Nonidentified responses in a proportional hazards setting

Research output: Contribution to journalArticlepeer-review

1 Scopus citations


Nonidentified response (NR), an important form of nonindependent censoring, is modelled in a proportional hazards setting. Methods to test for existence of and identify NR censored observations are developed. Incorporation of NR censoring information into appropriate algorithms can improve parameter and underlying baseline hazard estimation. Application to estimating time until death from AIDS is made.
