MatchIt: Nonparametric Preprocessing for Parametric Causal Inference

open access: yesJournal of Statistical Software, 2011
MatchIt implements the suggestions of Ho, Imai, King, and Stuart (2007) for improving parametric statistical models by preprocessing data with nonparametric matching methods.

Robustness of Some Nonparametric Procedures in Linear Models

open access: yesThe Annals of Mathematical Statistics, 1968
For the random variables $X_{ij}(i = 1, \cdots, N; j = 1, \cdots, r)$ consider the linear model \begin{equation*}\tag{1.1} X_{ij} = \mu + \beta_i + \tau_j + Y_{ij} (\sum \beta_i = 0, \sum\tau_j = 0),\end{equation*} where the $\tau$'s are treatment effects, the $\beta$'s are nuisance parameters (block effects), and the $Y_{ij}$'s are error components ...

On robustness and local differential privacy [PDF]

open access: yesAnnals of Statistics, 2022
It is of soaring demand to develop statistical analysis tools that are robust against contamination as well as preserving individual data owners' privacy. In spite of the fact that both topics host a rich body of literature, to the best of our knowledge,

Sea state estimation based on vessel motion responses: Improved smoothness and robustness using Bézier surface and L1 optimization

open access: yesMarine Structures, 2021
Floating structures oscillate in waves, where these wave-induced motions may be critical for various marine operations. An important consideration is thereby given to the sea states at the planning and operating stages for an offshore project.

Customized yet Standardized Temperature Derivatives: A Non-Parametric Approach with Suitable Basis Selection for Ensuring Robustness

open access: yesEnergies, 2021
Previous studies have demonstrated that non-parametric hedging models using temperature derivatives are highly effective in hedging profit/loss fluctuation risks for electric utilities.

Comparison the Robust Estimators Nonparametric of Nonparametric Regressions

open access: yesTikrit Journal of Pure Science, 2023
In order to get rid of or reduce the abnormal values ​​of some phenomena that may be the reason for not obtaining the desired results. This makes us to get conclusions far from reality for the phenomenon we are studying. That the traditional nonparametric estimators are very sensitive to anomalous values, which prompted us to use the fortified ...

Robust nonparametric regression: A review

open access: yesWIREs Computational Statistics, 2019
AbstractNonparametric regression methods provide an alternative approach to parametric estimation that requires only weak identification assumptions and thus minimizes the risk of model misspecification. In this article, we survey some nonparametric regression techniques, with an emphasis on kernel‐based estimation, that are additionally robust to ...

Robust Nonparametric Inference

open access: yesAnnual Review of Statistics and Its Application, 2018
In this article, we provide a personal review of the literature on nonparametric and robust tools in the standard univariate and multivariate location and scatter, as well as linear regression problems, with a special focus on sign and rank methods, their equivariance and invariance properties, and their robustness and efficiency.

Mortality Forecasting: How Far Back Should We Look in Time?

open access: yesRisks, 2019
Extrapolative methods are one of the most commonly-adopted forecasting approaches in the literature on projecting future mortality rates. It can be argued that there are two types of mortality models using this approach.

Outliers vs Robustness in Nonparametric Methods of Regression

open access: yesActa Universitatis Lodziensis. Folia Oeconomica, 2018
The article addresses the question of how robust methods of regression are against outliers in a given data set. In the first part, we presented the selected methods used to detect outliers.
