Likelihood ratio tests for the one-sided multivariate problem have non-monotone rejection regions and non-monotone power functions when correlation is present. This paper proposes an alternative test which is cone order monotone with respect to the positive orthant.

We suggest a new simple approach for estimation and assessment of covariate effects for the cumulative incidence curve in the competing risks model. We consider a semiparametric regression model where some effects may be time-varying and some may be constant over time. Our estimator can be...

We propose a semiparametric random effects model for multivariate competing risks data when the failures of a particular type are of interest. Under this model, the marginal cumulative incidence functions follow a generalized semiparametric additive model. The associations between the...
