Composite Goodness-of-fit Tests with Kernels

1 code implementation19 Nov 2021 Oscar Key, Arthur Gretton, François-Xavier Briol, Tamara Fernandez

Model misspecification can create significant challenges for the implementation of probabilistic models, and this has led to development of a range of robust methods which directly account for this issue.

Kernelized Stein Discrepancy Tests of Goodness-of-fit for Time-to-Event Data

no code implementations ICML 2020 Tamara Fernandez, Nicolas Rivera, Wenkai Xu, Arthur Gretton

Survival Analysis and Reliability Theory are concerned with the analysis of time-to-event data, in which observations correspond to waiting times until an event of interest such as death from a particular disease or failure of a component in a mechanical system.

Survival Analysis

A kernel log-rank test of independence for right-censored data

1 code implementation8 Dec 2019 Tamara Fernandez, Arthur Gretton, David Rindt, Dino Sejdinovic

We introduce a general non-parametric independence test between right-censored survival times and covariates, which may be multivariate.
