Marie Lecrosnier-WittkowskyRegression modelling of interval censored data based on the adaptive ridge procedure
Olivier Bouaziz, Eva Lauridsen & Grégory Nuel
A new method for the analysis of time to ankylosis complication on a dataset of replanted teeth is proposed. In this context of left-censored, interval-censored and right-censored data, a Cox model with piecewise constant baseline hazard is introduced. Estimation is carried out with the expectation maximisation (EM) algorithm by treating the true event times as unobserved variables. This estimation procedure is shown to produce a block diagonal Hessian matrix of the baseline parameters. Taking advantage...
