Selection Consistency of Lasso-Based Procedures for Misspecified High-Dimensional Binary Model and Random Regressors

open access: yesEntropy, 2020
We consider selection of random predictors for a high-dimensional regression problem with a binary response for a general loss function. An important special case is when the binary model is semi-parametric and the response function is misspecified under

Evaluating performance of covariate-constrained randomization (CCR) techniques under misspecification of cluster-level variables in cluster-randomized trials

open access: yesContemporary Clinical Trials Communications, 2021
Covariate constrained randomization (CCR) is a method of controlling imbalance in important baseline covariates in cluster-randomized trials (CRT). We use simulated CRTs to investigate the performance (control of imbalance) of CCR relative to simple ...

Model misspecification [PDF]

open access: yesStatistical Modelling, 2008
A common problem in statistical modelling is to distinguish between finite mixture distribution and a homogeneous non-mixture distribution. Finite mixture models are widely used in practice and often mixtures of normal densities are indistinguishable from homogenous non-normal densities.

An improved multiply robust estimator for the average treatment effect

open access: yesBMC Medical Research Methodology, 2023
Background In observational studies, double robust or multiply robust (MR) approaches provide more protection from model misspecification than the inverse probability weighting and g-computation for estimating the average treatment effect (ATE). However,

Environmental public good provision under robust decision making [PDF]

open access: yes, 2016
We study public good provision in a two-country dynamic setup with environmental externalities. In this framework, we examine robust decision making under potential misspecification of the process that describes the evolution of the environmental ...

A critical re-evaluation of the regression model specification in the US D1 EQ-5D value function

open access: yesPopulation Health Metrics, 2012
Background The EQ-5D is a generic health-related quality of life instrument (five dimensions with three levels, 243 health states), used extensively in cost-utility/cost-effectiveness analyses.

Which misspecifications persist?

open access: yesTheoretical Economics, 2023
We use an evolutionary model to determine which misperceptions can persist. Every period, a new generation of agents use their subjective models and the data generated by the previous generation to update their beliefs, and models that induce better actions become more prevalent.

Interpretation and Semiparametric Efficiency in Quantile Regression under Misspecification

open access: yesEconometrics, 2015
Allowing for misspecification in the linear conditional quantile function, this paper provides a new interpretation and the semiparametric efficiency bound for the quantile regression parameter β (

Bootstrap confidence sets under model misspecification [PDF]

open access: yes, 2014
A multiplier bootstrap procedure for construction of likelihood-based confidence sets is considered for finite samples and a possible model misspecification. Theoretical results justify the bootstrap validity for a small or moderate sample size and allow

An Information Criterion for Auxiliary Variable Selection in Incomplete Data Analysis

open access: yesEntropy, 2019
Statistical inference is considered for variables of interest, called primary variables, when auxiliary variables are observed along with the primary variables.
