A general framework for the analysis of kernel-based tests

no code implementations31 Aug 2022 Tamara Fernández, Nicolás Rivera

Kernel-based tests provide a simple yet effective framework that use the theory of reproducing kernel Hilbert spaces to design non-parametric testing procedures.

A Multiple kernel testing procedure for non-proportional hazards in factorial designs

no code implementations15 Jun 2022 Marc Ditzhaus, Tamara Fernández, Nicolás Rivera

In this paper we propose a Multiple kernel testing procedure to infer survival data when several factors (e. g. different treatment groups, gender, medical history) and their interaction are of interest simultaneously.

Survival Analysis

A kernel test for quasi-independence

no code implementations NeurIPS 2020 Tamara Fernández, Wenkai Xu, Marc Ditzhaus, Arthur Gretton

We consider settings in which the data of interest correspond to pairs of ordered times, e. g, the birth times of the first and second child, the times at which a new user creates an account and makes the first purchase on a website, and the entry and survival times of patients in a clinical trial.

Posterior Consistency for a Non-parametric Survival Model under a Gaussian Process Prior

no code implementations7 Nov 2016 Tamara Fernández, Yee Whye Teh

In this paper, we prove almost surely consistency of a Survival Analysis model, which puts a Gaussian process, mapped to the unit interval, as a prior on the so-called hazard function.
