To investigate the effect of such dropout, we consider two types of selection model: the first allows dropout to depend directly on...</p>

We propose a semiparametric multilevel survival model for clustered duration data in which the effect of a continuous covariate is represented by an unspecified, possibly non-linear, function. This model makes no distributional assumption about the cluster level random effects. The performance...

Basic and extended models are introduced to represent the properties of a binary accuracy indicator. Under specified assumptions, it is shown that an...</p>
