Covariate adjusted nonparametric methods under propensity analysis

open access: yesFrontiers in Applied Mathematics and Statistics
Propensity score is one of the most commonly used score functions in adjusting for covariates effect in statistical inference. It is important to understand the impact with propensity score in case some of the prespecified covariates are severely ...

Nonparametric Reconstruction of the Om Diagnostic to Test ΛCDM

open access: yesGalaxies, 2016
In this work, we consider an Om diagnostic using a non-parametric reconstruction by employing the Loess–Simex factory. This procedure allows us to perform a model-independent comparison for w(z) with the astrophysical data.

Nonparametric Inference in Mixture Cure Models

open access: yesProceedings, 2018
A completely nonparametric method for the estimation of mixture cure models is proposed. Nonparametric estimators for the cure probability (incidence) and for the survival function of the uncured population (latency) are introduced.

A simple non-parametric goodness-of-fit test for elliptical copulas

open access: yesDependence Modeling, 2017
In this paper, we propose a simple non-parametric goodness-of-fit test for elliptical copulas of any dimension. It is based on the equality of Kendall’s tau and Blomqvist’s beta for all bivariate margins.

Comparing survival curves based on medians

open access: yesBMC Medical Research Methodology, 2016
Background Although some nonparametric methods have been proposed in the literature to test for the equality of median survival times for censored data in medical research, in general they have inflated type I error rates, which make their use limited in
